The std.regexp functions instanciate a RegExp object, passing the argument
string to the constructor, then compile the regexp object to a more efficient
internal form and then call the corresponding method and finally return the
result. That helps the D programmer to write more concise code.

Like this :
# RegExp aFunction ( char [] aString )
# {
#      auto regexp = new RegExp ( aString ); 
#      regexp.compile ();
#      return regexp.aMethod ();
# }
