Maybe a patch which works.

Well this is way to improve the current isNumeric function.

It works well for these kinds of numerics :

(+/-) 1, 1L, 1UL, 1i, 1Fi, 1Li, 1F
1.55
1e+52
1_500_250

nan, nani, nan+nani


(+/-) inf


At least, this patch correct bugs found in the std.isNumeric function.

Sure we can (should !) improve it but at least it works (except for numerics
like .5e-52 but 0.5e-52 works)
