--- Comment #2 from John Colvin <john.loughran.colvin at gmail.com> ---
Seems like this is still happening:

auto foo()
{
    import std.regex : regex, matchFirst;
    const r = regex("asdf");
    matchFirst("fdsaf", r);
}

test.d(5): Error: template std.regex.matchFirst cannot deduce function from
argument types !()(string, const(Regex!char)), candidates are:
/usr/local/Cellar/dmd/2.072.0/include/dlang/dmd/std/regex/package.d(934):      
 std.regex.matchFirst(R, RegEx)(R input, RegEx re) if (isSomeString!R &&
is(RegEx == Regex!(BasicElementOf!R)))
/usr/local/Cellar/dmd/2.072.0/include/dlang/dmd/std/regex/package.d(942):      
 std.regex.matchFirst(R, String)(R input, String re) if (isSomeString!R &&
isSomeString!String)
/usr/local/Cellar/dmd/2.072.0/include/dlang/dmd/std/regex/package.d(950):      
 std.regex.matchFirst(R, String)(R input, String[] re...) if (isSomeString!R &&
isSomeString!String)
/usr/local/Cellar/dmd/2.072.0/include/dlang/dmd/std/regex/package.d(957):      
 std.regex.matchFirst(R, RegEx)(R input, RegEx re) if (isSomeString!R &&
is(RegEx == StaticRegex!(BasicElementOf!R)))
