Do you realize you can do "local <toclose> x = ctx.__enter()" ( and
have enter return either self or a helper object )

I think the behaviour is enough, mechanism, you cannot do the
equivalent of <toclose>, but enter is trivial and in fact there are
things like Java which are dessigned to work this way ( try with
resources, which is very similar to <toclose> ).

Then do it, it is simple. do, local toclose = file.open, for loop with
may break , some things wihich happen after it, end. No need for enter
anywhere.
