Using of
<table scope> ::=
[<global or local>] [TEMPORARY]
won't make a big difference.
Yes it does, this would introduce a semantic ambiguity (and probably a
syntactic ambiguity. In the original syntax, LOCAL (not supported by
Firebird) and GLOBAL are modifiers of TEMPORARY. You are now introducing
it as a separate element, with two different meanings.
For example, should the definition of a global temporary table be
replicated or not?
If such a feature is to be introduced, it should not be a kludge that
obfuscates/overloads standard syntax.
