[issue4134] Peephole optimization: returning a temp

[Raymond Hettinger]

Raymond Hettinger <rhettinger at users.sourceforge.net> added the comment:

Sorry, am not excited by this one.  It is not a common idiom in most
code that I've ever seen and it never occurs in an inner-loop.  Besides
the load_fast/store_fast combination are so *very* fast that any real
code would not see a worthwhile speedup.

When the AST optimizer gets built-out, I expect that we'll get many of
these sort of optimizations for free.  In the meantime, this one just
isn't worth adding complexity to the peepholer.
