The underlying problem is that symbols names grow quadratically when combining
templated ranges, because each range's name is a template argument to the next
range. Sometimes name occur twice, as template argument and return type.
An obvious solution to the problem is to adopt a compression scheme similar to
C++ mangling on Windows.

This is a well known and important problem but has a lower priority than many
other issues. You can help to solve it by opening a bugzilla issue (might
already exist) and finding out how to integrate such a backreference compression
with D's current mangling.

D already does (for Win32) a generic compression on names. It works a lot better
than poorly reinventing compression - it's far less complex, less buggy, easier
to implement, etc.
I'd support adding a Win32-like compressor. The change I'd make is having it
only use identifier characters for the compressed result.
