Oh yes, I remember when we all tried ;)

But (just as a data point) it's amazing what LuaJIT can do with code
that any Lua programmer would see as 'inefficient'.

For instance, have a look at Lua Fun:

Will work on stock Lua (with one small change). But the generated
machine code for that 'functional' expression is most impressive.

Whether it is more _readable_ I leave as another question...
