But, those don't work because T is a Tuple of the types. Is there some trait combination I can use to do this? Something like (obviously made up)...

all(TemplateArgsOf!T, t => isIntegral!t || isSomeString!t)

Thanks!

import std.meta: allSatisfy, Or = templateOr;
allSatisfy!(Or!(isIntegral, isSomeString), T);
