           Summary: 0b and 0x prefixes for std.string.isNumeric

This is almost an enhancement request.

I think std.string.isNumeric should see the 0b and 0x prefixes as parts of a
number literal:


import std.stdio: writeln;
import std.string: isNumeric;
void main() {
    isNumeric("0x10").writeln();
    isNumeric("0b1010101").writeln();
}


With dmd 2.062 prints:

false
false


Expected:

true
true
