The symbol length problem has been greatly reduced by Rainer's recent
mangle PR, which is now in git master and will be in the following
release. There is still room for even more reduction but they will be
comparatively minor. Rainer's fix has eliminated the bulk of the symbol
length problem.

The CTFE problem will be fixed soon, once Stefan Koch finishes his
newCTFE engine.

Templates are still an area where a lot of improvement can be made. But
Stefan has indicated interest in visiting this area in the compiler
after the newCTFE project is done.  So eventually we'll get there.
