[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.

// Here we also test "functions that just wrap other functions" like in camel1.tolk,
|
||||
// but when they reorder arguments, e.g.
|
||||
// > T f(x,y) { return anotherF(y,x); }
|
||||
// This also works, even for wrappers of wrappers, even if anotherF is asm(with reorder).
|
||||
// But swapping arguments may sometimes lead to bytecode changes (see test2),
|
||||
// both with compute-asm-ltr and without it.
