[Tolk] v0.6 syntax: fun, import, var, types on the right, etc.
Lots of changes, actually. Most noticeable are: - traditional //comments - #include -> import - a rule "import what you use" - ~ found -> !found (for -1/0) - null() -> null - is_null?(v) -> v == null - throw is a keyword - catch with swapped arguments - throw_if, throw_unless -> assert - do until -> do while - elseif -> else if - drop ifnot, elseifnot - drop rarely used operators A testing framework also appears here. All tests existed earlier, but due to significant syntax changes, their history is useless.
