Hello.

How do you determine if a type is an array? I saw the hack in std.boxer 
but was wondering if there is a language standard / better way.

Regards,

Myron.

Here's what I would do.
template isArray(T) { const isArray=false; }
template isArray(T: T[]) { const isArray=true; }

Beware though, this was not extensively tested. From what I can see, it
_should_ work, and also does in simple test cases, but that's no guarantee.

Use it like "[static] if (isArray!(Type)) { do stuff here } "
