Am I the only person that worries greatly about the length of symbols

No, I do as well. My units of measurement project suffered from very
non-negligible code bloat due to symbol name length, and even if that
was a rather extraordinary endeavor to begin with, "normal" D code is
affected just as well. For example, try this one from the std.algorithm
unit tests:

That's 13 kilobytes of data for a single symbol name! And the whole file
also crashes the MinGW as when debug info generation is enabled, with
the following rather hilarious error message:
"Fatal error: can't close
N:/Build/Work/ldc2-llvm3.3-release/runtime/phobos_std_algorithm_debug.o:
File too big"
That's just insane.
