Instance Method Details

#evaluate(scope) ⇒ Object

we’re returning self here to wrap the regexp and to be used in places where a string would have been used, without modifying any client code. For instance, in many places we have the following code snippet:

val = @val.safeevaluate(@scope) if val.match(otherval) ... end 

this way, we don’t have to modify this test specifically for handling regexes.
