For me is ugly to see a procedure call like Foo()
=====================================
For instance, TCL solves this problem by enclosing subroutine calls in
square braces :
proc get_res {param1 param2} {
return [expr $param1 * $param2]
}
set res [get_res 3 4]
And assigning from other variable :
set res 12345
set res_1 $res
PS:
BTW, accessing values of variables via a special sign ("$" mainly') is
excellent feature:
set res_var $input_var
