Original sentence: Code coverage tests may fail to detect such errors because the combination of all places where values are created and all places where a certain value is used must be taken into account.Some statically typed languages have a "loophole" in the programming language specification that enables programmers to write pieces of code that circumvent the default verification performed by a static type checker.Static typing is a limited form of program verification (see type safety): accordingly, it allows many errors to be caught early in the development cycle
Edited sentence: Code coverage tests may fail to detect such type errors because the combination of all places where values are created and all places where a certain value is used must be taken into account.Static typing is a limited form of program verification (see type safety): accordingly, it allows many type errors to be caught early in the development cycle.The most widely used statically typed languages are not type safe.They have "loopholes" in the programming language specification enabling programmers to write code that circumvents the verification performed by a static type checker and so address a wider range of problems
