How Nim's way assign variable in or beside other expression at once, the one that'd always led to:
Error: expression 's = "foo"' has no type (or is ambiguous)
when trying like c/c++ code if (s = "foo").len > 5 { cout<< "Yes" ;}
or some else?
the point was that, how to have variable assignment in some expressions at once,
if (let s = "foo"; s).len > 5:
echo "Yes"
or
var s: string
if (s = "foo"; s).len > 5:
echo "Yes"
