Re: [Pyparsing] Proposed notational shortcut for setResultsName

[Corrin L. <Cor...@da...>]

A tiny modification of Ralph's suggestion makes the most sense to me
=20
    userdata =3D Word(alphas, res =3D "name") + Word(nums+"-", res =3D
"socsecno")

It just seems odd to use getitem to "set" something, i.e. the results
name.  What about having "_" as an attribute function instead so it
isn't too obtrusive?

    userdata =3D Word(alphas)._("name") + Word(nums+"-")._("socsecno")

Or

    userdata =3D Word(alphas, n =3D "name") + Word(nums+"-", n =3D =
"socsecno")

Cheers,


Ralph.
