This little sample code can't get compiled if the ctRegex! version is used (DMD
2.065):

=====*=====*=====*=====*=====*=====*=====*=====*
import std.stdio;
import std.regex;

void main() {
    auto s0 =
`url:"http://download.microsoft.com/download/Windows8.1-KB000000.msu"`;
    auto s1 =
`url:"http://download.microsoft.com/download/Windows8.1-KB000000.exe"`;

    //~ C:\Bin\DMD2\windows\bin\..\..\src\phobos\std\regex.d-mixin-5885(6214):
Error: found 'else' instead of statement
    //~ auto rx =
ctRegex!(`url:"(http://download.microsoft.com/download.+?(msu|exe))"`);

    // This works fine as expected, instead...
    auto rx =
regex(`url:"(http://download.microsoft.com/download.+?(msu|exe))"`);

    writeln(match(s0, rx).empty());
    writeln(match(s1, rx).empty());
}
