I'm really glad they were overall favorable.

Nothing is perfect, but I think it's very reasonable We have a general solution using leading "\\" that easily handles all cases, and <*...*> is a useful shorthand for handling let statements with short variable-definition blocks. > As a complete aside, in Haskell, there's a special "fallback" rule > where an error due to indentation matching will cause the parser to > attempt to close a group.

I think "if" looks great: if {x < y} ! x ! y Obviously if you want a *keyword* to mark the else clause, that doesn't do it, but in that case "cond" is the better choice anyway. --- David A.
