I once hacked up some metatable magic to allow writing pseudo-infix
operators like:

x = ((4) '<<' (3)) '|' (y)

It's ugly and inefficient, but it works! Probably biggest drawback is
not only the operators need to be quoted (since they're strings), but
the parameters need to be in parentheses (since they're either being
called or being function arguments), so it becomes bracket hell
quickly...

Really love to have real bit operators in Lua.
