temporarly disable the # ... # comment
it clashes with the shebang, the initial #! should be excluded... Dunno how thought.
fix the indentation for the conformity clause
pretty name for the CASE on a UNION value
rework the grammar
In Algol68 pretty almost everything seems to yield a value (except loops, mode declarations and... ?) so it's easier (and probably more correct) to have "exprs" instead of "insts" (instructions) everywhere. The "resolvers" are probably wrong, but so far they work.
simplify the a68-comment-style defcustom
It doesn't really make sense to ask for both the initial and closing comment delimiter when they are always the same, just ask for one of o # o CO o COMMENT
correctly highlight comments
Algol68 support three styles of comments: 1) COMMENT ... COMMENT 2) CO ... CO 3) # ... # These can't be nested, although you can have things like COMMENT CO ... CO COMMENT as a whole comment because from `COMMENT' up to the next closer `COMMENT' is a single comment (duh.)
