Should I stop being interested in D language if I don't like to see template instantiation in my code?

I'd suggest learning to love it, or at least getting to it, vs.
to<ushort>(args[1]) C++ syntax. Template *syntax* benefits are
1. D's is relatively quick to parse.
2. the ! is an attention getter so you can see that some special
action is taking place (although templates don't always require
this). Personally this is more of a comfort ("I'm *definitely*
doing some work at compile-time here, instead of at runtime like
other languages force me to") than an alert ("something weird is
happening!") though.
3. it's very clear what's a compile-time vs. a runtime parameter
to
the template.

Templates are so beneficial that people put up with C++.
D uses them everywhere and if you persist in hating the
syntax you'll just hate a lot of the D syntax that you see.
