import std.string: strip;
void main() nothrow {
    " hello ".strip;
}



dmd 2.064beta gives:

test.d(3): Error: 'std.string.strip!(immutable(char)).strip' is not nothrow
test.d(2): Error: function 'D main' is nothrow yet may throw


I don't know if this can be done. Often string functions need to decode UTF,
and this could raise exceptions. In most cases, or for ASCII strings, a strip
can't throw exceptions.

If this can't be done then please close down this issue.
