newRPL already has scoped locals, you can define a scope any time using :: ; (in addition of the classic syntax: -> var1 ... varn << ... >> )

Code:


<<
1 'a' LSTO
@ FROM NOW ON 'a' EXISTS IN THIS << >> BLOCK
::
@ 'a' STILL EXISTS IN HERE
1 'b' LSTO
@ 'b' EXISTS FROM HERE ON, BUT ONLY WITHIN THE :: ; DELIMITERS
;
@ 'b' NO LONGER EXISTS HERE, BUT 'a' STILL DOES
>>
@ 'a' NO LONGER EXISTS HERE
