Hello Tom,
That's probably a bigger change than we want to be putting in right now,
though I'm a bit tempted to go try it.
I definitely agree that the text variable solution is pretty ugly, but it
was the minimum change solution, and I do not have much time available.
Well, I felt like doing some minor hacking, so I went and adjusted the
code to work this way. I'm pretty happy with the result, what do you
think?
This is a definite improvement.
I like the lazyness between string & numeric forms, and for sorting, that
is what was needed doing to have something clean.
Applied on head, it works for me.
While testing the patch I found a minor preexisting (mine...) bug: when
string-scanning doubles, whether the whole string is consumed or not is
not checked. This means that -D x=0one is interpreted as double 0.
I came up with the attached check, but maybe there is a cleaner way to do
that.
