This is the best way to accommodate everybody and their 'special
needs'.  I'd suggest looking into a new API for the token-filter patch
so (a) it has minimal impact on programs that don't need it (b) that
it cannot be accidently invoked by defining a global FILTER and (c)
that different token filters can co-exist.

BTW, I'm not particularly worried about |x| x*(x+1) not getting into
stock Lua, since the 'string lambda' form is perfect for the cases
where it is intended, which are _not_ closures, just one-line regular
functions.
