[VM/exec] Leakless blocks not working properly with pre-defined functions
Let's say we have a pre-defined function (e.g. arg) and this symbol is used
as an iterator variable - which is precisely where leakless blocks come into play -
this creates a total mess, since their arities are not properly handled.
e.g.

for arr 'arg [ 
; do sth
]

and https://github.com/arturo-lang/arturo/blob/master/examples/rosetta/variadic%20function.art
