Local Variable Scope

[HzanRsxa2959]

Sorry if this has been talked about before, but I didn't find any mention of it.

With the introduction of named local variables (#32), a way should be added add scope to them to avoid any potential name conflicts with opcode 0AB1.

@HzanRsxa2959 I think I understand what you are asking for, but can you please provide a few code examples where scoped variables are used?

@x87 Here is some example code with the issues commented:

Tested on Sanny Builder 3.7.0 released on 2021-1-30.

EDIT:
Also, I can't think of any example where nesting is necessary at all for scopes, at least in SCM.

another example

{$CLEO}

int x = 0
int y = 1
0AB1: cleo_call @fn 0

// cleo_call creates a local scope
:fn
int y = 1   // this is not the same 'y' as defined in the outer scope
cleo_return 0
