Description

Collection implements a method with the following signature:

public Object findResult(Closure closure)

It would be nice if a similar method existed for String.

public Object findResult(Pattern pattern, Closure closure)

The method find() almost performs the same function except that it converts the result to a string, even if it's null or a Boolean. Alternatively, the existing find() methods could be changed to return Object instead of String. Without this method, the matching string has to be saved into a temporary variable and then processed afterwards.

Example:
if (new File("file").text.findResult(~/VAR\s*=\s*(\S+)/)

{ it[1] != "VALUE1" }

) {
// ...
}
