Haczyk

Haczyk is a language where the variables barter based on the letters in their names.
==Name==
The name comes from haczyk, which was a Polish word according to English Wiktionary at the time the language was created, defined as informally meaning "catch, hidden disadvantage in a deal" and as the diminutive of hook. 
==Description==
=== Haczyk 0.1.0 ===
In Haczyk 0.1.0, the only datatype is an unordered dictionary. Each variable has an unordered dictionary which contains characters and corresponding numbers. The variables desire the characters which are in their name or which correspond to negative numbers.
Variables are assigned characters using the assignment operators +< which adds things and -< which takes things away. Each of these can be followed by a number between 0 and 9, where 0 indicates nothing was added or taken away, 1 indicates one of each character was added or taken away, etc.
name +<9 corn
causes the variable name to consist of an unordered dictionary where "c", "o", "r" and "n" correspond to 9.
Each time that a variable is assigned, the variables barter for characters they want, which include characters in their name or for which they have a negative number. For each character in its name, the variable checks if another variable has either the character in its name or a character for which it has a negative number, then checks if it has a character which the variable wants. If both of these are true, the variables trade characters.
There are if-statements and while-loops, where in practice, an if-statement is a while-loop which only runs once.
These loops always start with a question mark. Then there is either a number, which signifies the amount of times to loop, or another question mark, which signifies an infinite loop. Then there is a set of parentheses. Then on a new line, there can be other pieces of code, including other loops. Finally, at the very end, there is a single close bracket (there is no corresponding open bracket).
Example of an unconditional while-loop:
?100()//repeats 100 times unconditionally
name +<9 corn
)
//At the end, name contains 900 of "c", "o", "r", and "n".
==Not Turing-Complete==
In order to be Turing-complete, the language has to:
* be able to store data without changing itsome languages may be able to oscillate between two states of data with one state as padding
* be able to change conditionally
Haczyk 0.1.0 can't do the latter, only being able to loop conditionally. It cannot be Turing-complete for this reason. It might be able to do the former, because as long as the character doesn't appear in any other names, you can add the character to one variable over time.
==Implementation==
This is the implementation of Haczyk 0.1.0 which only has unconditional loops. It is probably not Turing-complete.

== Trivia ==
* Haczyk is possibly the only programming language which isn't alpha-equivalent. If you change a variable name, it has a legitimate and unavoidable effect on how the program runs.
* The name of this language came from the programming language Crazy, because it was meant to belong to a language based on that language. The idea behind the language came from the communism idea, but a satirization of capitalism instead of communism.
