The documentation to FORWARD (cf. "2.8. FORWARD") states among other things:
If you specify neither ARGUMENTS nor ARRAY, the language processor uses the
same arguments
specified on the original method call.
In the following UNKNOWN method the forward keyword statements do not contain
ARGUMENTS nor ARRAY
subkeywords, yet the arguments do not get forwarded:
::method unknown -- counts # of invocations
expose counter name
use arg msg, args
counter+=1
.stderr~say("#" .line": name="pp(name) "counter="pp(counter) "msg="pp(msg)
"args[1]="pp(args[1]) )
select case name
when "NoOp-input" then forward message (msg) to (.stdin)
when "NoOp-output" then forward message (msg) to (.stdout)
when "NoOp-error" then forward message (msg) to (.stderr)
end
.stderr~say("#" .line": .input="pp(.input~current)
".output="pp(.output~current) ".error="pp(.error~current))
Adding
ARGUMENTS (args)
to the forward statements will forward the received arguments.
Is this a bug in FORWARD or in its documentation?
