Why so complicated?

import std.regex;
void main()
{
    auto pattern =
regex(r"^(import|file|binary|config)\s+([^\(]+)\(?([^\)]*)\)?\s*$");
}

Taken from rdmd.

It fails cause it rejects \(
I suggest to turn line 1573 of regex.d (after case State.Escape:
switch(current))
into 'assert(0, "Unsupported escape character \\"~cast(char)current);' so one
gets a proper error message.
