An explicit 'del temp' ends the scope of the variable.  Its not much
more to type that any sort of brackets and allows for overlapping
scope of temporaries instead of artificially forcing nesting.  If you
want to extend the scope of 'temp', it is probably easier to get rid
of the explicit deletion than a pair of brackets.
