If I recall correctly, the current implementation of
std.net.isEmail was requested by you.
Regardless of whether it was requested by me or not, if the
current version is not working for us, we need to explore
alternatives.
The regex problem is being solved:

That's fixing just the "isEmail" issue which is good I guess.
But after reading this thread, I run some tests on one of my code
bases, which uses about 6 regex throughout.
Switching from ctRegex! to regex yielded a 50% build time
reduction, and from what I read even the normal regex are slowing
things down considerably.
Might need a warning on the docs for ctRegex! explaining it'll
screw your build times if you use it, unless there's some way to
speed that up to something normal.
Btw, my project which is 3517 lines of D builds in 20s disabling
the ctRegex on an i7 4770k at 4.3Ghz.
So I'd say once you start doing some more complex usages, D's
build speed goes out the door.
