This is the last one: combining an hypothetical getfenv with my short
lambda suggestion, we get
function table.in(tabl, func)
setfenv(func,tabl)
func( getfenv(2) )
return tabl
end
foo=3
local t = table.in( {}, (env):
bar = env.foo -- bar now == 3
baz = 5
::)
Most importantly, this doesn't add any new semantics to the language.
