FWIW I don't have any preference, as long as the variable can still
have a name (that is not a symbol).
A side question regardless of syntax. What do we do with
%(unrecognized name)/foo? I see three options
- expand to empty, so "/foo"
- keep it and try the literal path "%(unrecognized name)/foo"
- somehow tell the caller that the path is invalid and treat it like
non-existing path, even if there is some real thing at "%(unrecognized
name)/foo"
The last option is more predictable. But we need to be more careful
about the syntax because if "%(some path like this)" actually exists
somewhere, then it will be broken. And I think it's also more work.
