Having functions in std.ascii (and elsewhere) seems acceptable. But I think the
name of such functions shouldn't be too much long.


to!int raises exceptions. Returning -1 in case of errors seems able to cause
some problems. One common use case for the char->int conversion:

auto s = "123x456";
auto digits = s.map!numericValue().array();

Now I have to scan digits again looking for any -1.
