The first version invokes method Regexp#=~ and the second version 
invokes String#=~ - which happen to do roughly the same although I 
believe the second one to be a tad slower.  I personally prefer the 
first form because of the speed difference and regular expression 
matching is rather an operation of Regexp than of String.

Kind regards
