Why can I not use const/immutable regex?

I think it's a Phobos bug that can't use regex as immutable.

You can use const regex with getting rid of "const" attribute 
with cast().
    matchFirst( "big string", cast()r1 );

Or using enum seems better way. This style appears in Phobos's 
code.
    enum r1 = regex("bla");
