The docs are there, it just may be a little esoteric to find them.
:helpgrep \<foobar(
or maybe, to narrow down the search,
:vimgrep /\<foobar(/g $VIMRUNTIME/doc/version*.txt
will search, in the former case the text of all help files, or in the
latter case only that of the version*.txt helpfiles, for any mentioon of
the foobar() function. If it was added to Vim not earlier than version
4.0, you'll find at exactly at which version and patchlevel that happened.
If you find out that it was introduced at version 6.3.87 you can test
for it by either
if exists('*foobar')
or
if version > 603 || (version == 603 && has('patch087'))
The latter is useful if, at some point after introducing the function,
an important bug in it (that you care about) was fixed.
If some version of Vim 3 already had the function (i.e. it was already
there as other than a "new feature" in Vim 4.0.000), then I suppose you
can say by now that it's been there "forever", and the only case when
you might still be unable to use it is if you use a non-feature-complete
Vim lacking some optional feature which includes that function. Of
course, -eval versions include no functions at all.
Best regards,
Tony.
