Summary: upvar can create unusable variable

Initial Comment:
set scalar test
array set array {foo bar}
upvar 0 scalar array(grok)
set array(grok)
=> can't read "array(grok)": no such element in array

A scalar (link) variable named "array(grok)" has been
created, but there is no mechanism at the script
level for doing anything with it.

Seems [upvar] should fail rather than give something
that can't be used.
