It perfectly fine to use escapes for special characters:

import std.regex;
void main() {
    auto r = regex("[\]]");
}

The reason for killing first bracket doesn't count rule (if ever knew it
existed)
is that new regex allows doing things like 
[[abc0-9]--[bcd||1-9]] 
i.e. set operations 
the above should get you [bc0], it's more useful with \p{xxx} things.
Basically braces do matter more now. 
But this many other languages... (or better libraries) - which ones? Unless
there is strong precident I'm not doing another special case.
