Function: match

--Usage--
> match(some_string, match: regular expression)

Does a string match the given [[type:regex|regular expression]]?

When the match is performed many times with the same regular expression it is more efficient to declare that as a default argument:
> my_match := match@(match: "something")
> my_match("input") # called many times
This way the regular expression is only compiled once.

--Parameters--
! Parameter	Type			Description
| @input@	[[type:string]]		String to match.
| @match@	[[type:regex]]		Regular expression to match.

--Examples--
> match("aaaa", match:"a*")   == true
> match("a",    match:"b*")   == true
> match("abc",  match:"b+")   == true
> match("abc",  match:"$b+^") == false
>
> f := match@(match: "a+|b+")
> f("xyz")  == false
> f("aabb") == true
