Looking at CLHS "3.1.1.1 The Global Environment" we see at least 5,
and adding "3.1.1.3 Lexical Environments" we see 3 or 4 more (4 if
you count "compiler macros that are locally disabled"), for a grand
total of 8 or 9 at least. And Pekka Pirinen <pekka@harlequin.co.uk>
in <URL:news:ix6734k5a0.fsf@gaspode.cam.harlequin.co.uk> says you
should add structures, methods, method combinations, and SETF methods.
Some might even add LOOP keywords, since they can't be shadowed.
What's that now, 12? 13? But in any case, probably at least 11 or
12 of the following 13:
- Functions & macros
- lexical variables
- special variables
- types and classes
- GO tags
- block names
- structures
- SETF methods
- compiler macros
- methods
- method combinations
- declaration specifiers (not types, things like IGNORE, INLINE, etc.)
- (LOOP keywords?)
Not to mention that each defined package adds a nearly-full set of
additional namespaces.
