Re: Variables and parameters

/ Jeni Tennison <jeni@jenitennison.com> was heard to say:

| or variables.

Yes, but it puts variables/parameters and input/output labels all into
the same "symbol space" which worries me a bit.

| This is more flexible because it means that you can refer to more than one

Indeed. Is that valuable enough to warrant the added complexity?
