(For my purposes, I'd add basic support for functions. It was easy enough
in your new setup. The reason is that I use local helper functions a lot,
but find it annoying when I need to type "begin return; end Whatever;"
again and again. It would be all right for me to type the parameter profile
into this basis template, just like in conditionals. '_' in the function
skeleton could place the cursor accordingly.
(That should be "return NAME;", now that I think of it, just like
gnatstub's scheme, restricted to NAME (from `str').
(Writing Ada 2005 containers' Iterate, Query_*, and Update_*
also incurs writing some procedures routinely, so maybe there is a case
for procedures, too.)

I tried, somewhat naively, to allow "[Foo]" as a statement. It worked.
Indentation seems to work, that is. To this end, I made two changes:
(1) Characters '[' and ']' have comment syntax,
+ (modify-syntax-entry ?\[ "<]" table)
(modify-syntax-entry ?\\ "." table); default is escape; not correct for
Ada strings
+ (modify-syntax-entry ?\] ">[" table)
(2) A corresponding production, and then its non-terminal is added to the
production for "statement", in ada-grammar.wy.
