Nothing like this will be accepted without performance data.  I very
much doubt that these will improve anything (actually, I expect it the
other way round).  Find out what the average distribution of string
lengths etc is and make up a test suite.  You'll most probably see
that all the startup costs are far too high.  This is especially true
for nonsense like MMX.
