Coming from D.learn where someone asked for some automatism to

The OP wasn't looking for other benefits of the template
version other than argument checking and didn't consider the
downsides either. So maybe there is room for improvement using
runtime arguments.
So let's add some features:
1) compile-time "in" contract, run on the argument list
2) functionality to promote runtime arguments to compile-time
This was the more precise question:
How to "promote runtime arguments to compile-time".
I forgot the exact error, but it was during using vibe.d, that
there
was an error popping up at runtime, which I thought should have
been detected as simple syntax violation already during compile
time.
Making me feeling for some seconds being back at .php. :)
I think it was in a regex, where the use of ctRegex would have
prevented me from
the runtime error.
And last but not least: Thank you Marco for sharing your thoughts
and expertise!
