Quoting myself from the prior thread:

"I want to point out the reasons why Python requires a control
structure but Lua would not: Python's locals are function-scoped.
Declaring a local in Python means it doesn't go out of scope until the
function returns. For this reason, Python requires an explicit control
structure to define the lifetime of the variable. Lua does not have
this limitation."

They absolutely needed another control structure to implement their
flavor of RAII.
