I've been looking for a way to make my .vimrc slightly more portable
across machines with variously vendor-crippled vim packages, usually
approximating a "tiny" build. I've tried adding a :finish call before
anything that triggers exceptions, like so:
if !has('eval')
finish
endif
...but it seems that :finish is among the features omitted in some of
these builds! (The call generates an E319.) Are there any similarly
concise alternatives to just wrapping everything in has() blocks?

Tiny builds have the :finish command all right, what they lack is
expression-evaluation, which is needed for the :if statement. So, in a
tiny build, the whole scope of an :if statement, from :if to :endif, is
handled as a nestable comment, see ":help no-eval-feature".
To make sure your script isn't sourced by tiny builds, just wrap the
whole script in ":if 1" ... ":endif".
OTOH, in order to have some statements interpreted _only_ by builds
without expression evaluation, place them at the end of your script,
this way:
if 1
finish
endif
" come here only with Vim builds without expression evaluation
Best regards,
Tony.
