 From what I've observed, generating the long symbol name itself 
is fast. If we avoid the deep type hierarchy, then I think indeed 
you can expect compile time improvement.

MD5 hashing slowed down builds by a few percent for Weka (note: 
LDC machinecodegen is slower than DMD's, so percentage-wise...), 
which can then be compensated for using PGO ;-)  /+  <--
