Comment out the call to `regex()`, and I get:

how long you think this takes to compile?

I was surprised at this, then I looked at the first line of
isEmail:
static ipRegex =
ctRegex!(`\b(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}`~
`(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$`.to!(const(Char)[]));
So it's really still related to regex.
That’s really bad idea - isEmail is template so the burden of
freaking slow ctRegex
is paid on per instantiation basis. Could be horrible with
separate compilation.
