I was thinking of doing that but I did not want to cause confusion. i.e. if ...
then ... elsif ... else ... end if   vs. ifdef ... then ... elsifdef ... end
ifdef

I like elsif better and it would reduce one keyword count, but I'm not sure
about it's clarity? Also, it would then blend in better with other standard
if/elsif/end if statements? Thinking aloud seeking input.

Now that the functionality exists, it's easy to change its syntax. This is what
Open Source software is about, isn't this great? Ideas implemented, improved and
furthered.
