" There are 72 reserved words in total in Ada2005. Some keywords are
" used in more than one way. For example:
" 1. "end" is a general keyword, but "end if" ends a Conditional.
" 2. "then" is a conditional, but "and then" is an operator.
"

" We'll highlight the standard exceptions, similar to vim's Python mode.
" It's possible to redefine the standard exceptions as something else,
" but doing so is very bad practice, so simply highlighting them makes sense.

" We don't normally highlight types in package Standard
" (Integer, Character, Float, etc.). I don't think it looks good
" with the other type keywords, and many Ada programs define
" so many of their own types that it looks inconsistent.
" However, if you want this highlighting, turn on "ada_standard_types".
" For package Standard's definition, see ARM section A.1.
