Closes #XXXXX

This adds support to the Function regex in order to handle functions like

function myFunc(arg1 : string, arg2 : string) : string{
}

which won't match under the current set of helpers. Additionally there are no breaking changes if the tests are to be believed.

what's the difference between . and [\w\W]?

[a2937]

I panicked. They're probably identical. I could probably have used only the one regex symbol rather than both.

[a2937]

Okay I tried something a little less extreme and added tests for the other regex. How's it look?

[majestic-owl448]

could you try instead adding the pattern for types? adding something that can match anything seems dangerous

[a2937]

Please tell me this is close to what you meant. My goal was to make it so that way there's a function specifically there for Typescript Types. And it could be modified such that specific types can be added as a parameter.

We are thinking of adding AST-based helpers for TypeScript as well. So this might not be necessary. I'll keep you posted.
