 heuristics to get something which "looks nice"... and ML systems have become
 very good at heuristics. Also, we've got huge piles of training data — just
 choose some high quality, tastefully hand-formatted libraries.

 * We use flags rather than child nodes to represent the difference between `struct` and `mutable struct`, `module` and `baremodule` (#220)
 * Iterations are represented with the `iteration` and `in` heads rather than `=` within the header of a `for`. Thus `for i=is ; body end` parses to `(for (iteration (in i is)) (block body))`. Cartesian iteration as in `for a=as, b=bs body end` are represented with a nested `(iteration (in a as) (in b bs))` rather than a `block` containing `=` because these lists of iterators are neither semantically nor syntactically a sequence of statements, unlike other uses of `block`. Generators also use the `iteration` head - see information on that below.
 * Short form functions like `f(x) = x + 1` are represented with the `function` head rather than the `=` head. In this case the `SHORT_FORM_FUNCTION_FLAG` flag is set to allow the surface syntactic form to be easily distinguished from long form functions.
-* All kinds of updating assignment operators like `+=` are represented with a single `K"op="` head, with the operator itself in infix position. For example, `x += 1` is `(op= x + 1)`, where the plus token is of kind `K"Identifer"`. This greatly reduces the number of distinct forms here from a rather big list (`$=` `%=` `&=` `*=` `+=` `-=` `//=` `/=` `<<=` `>>=` `>>>=` `\=` `^=` `|=` `÷=` `⊻=`) and makes the operator itself appear in the AST as kind `K"Identifier"`, as it should. It also makes it possible to add further unicode updating operators while keeping the AST stable.
