Folks, I think we have reached a point where a revised I-D for the
variables document is in order. I'm starting to lose track of
where we are on some of these changes...
I fully agree, but I'd like some feedback on a very important issue
first, the syntax vs. semantics issue.
semantics seems the easier bolt-on, but syntax is the smoothest change
IMO. in particular, the backslash handling feels more natural.
consider "\${foo}". if we change syntax, the backslash will quote the
dollar so that it isn't a variable reference. if we change semantics
of strings, the backslash has no effect.
The gut reaction of a shell programmer will probably differ,
but I'd rather not change the syntax. To me, string scanning
and variable extension are different stages and must not
affect each other.
I fully agree with this.
