Clean Up Old Comments and Commented-Out Code

If any of these removed chunks are important, I'll gladly revert them!
From [Comma Operator][1],

> The `=>` operator is a synonym for the comma except that it causes a word on its left to be interpreted as a string if it begins with a letter or underscore and is composed only of letters, digits and underscores. This includes operands that might otherwise be interpreted as operators, constants, single number v-strings or function calls. If in doubt about this behavior, the left operand can be quoted explicitly.

My prior understanding stopped at the first sentence I guess so I did not thin it would include the dash.  Even after reading that though it's only barely clear to me that it might include the dash.
