I think this also could simplify the syntax including bug #3672.
- one $ (ex. $var, $return): returns the value of var or return value.
- two $ (ex. $$var, $$return, $$*): returns the values with variable names.
- more than two $ (ex. $$$var, $$$*): returns the values ($ means the depth of
nesting) with variable names.
And the simple syntax also simplifies parser :-) (don't requires 'suffix' parsing)
Thank you,
