Hmm, did a once-through read. I think the whitespace-significant
stuff in wart is a little complicated, especially with rules regarding
"indent by one space", which continues the line, and "indent by two
spaces", which creates a sublist.
So far, in sweet-expressions, once inside a ( [ or { indentation is
ignored, and is only noticed again upon exiting the } ] ).
Also, using keywords seems to require parentheses. Our current
solution (going through some serious debate) is to allow a syntactic
symbol that basically says "pretend we indented here, so ignore the
spaces after this point", currently proposed to use \ (or . or group).
So your "if :else" example could be rendered as:
if
. {1 iso {x % 2}}
. \ 'odd
. :else
. \ 'even
which doesn't need parentheses, either.
Sincerely,
AmkG
