0. yes to (for|if)* - also for generator expressions
1. Array comprehensions with for/if do not look very readable -
the generators and filters seem to merge into one blob of text.
[x*y for x of range(XDIM) if x&1 for y of range(YDIM)]
While syntax highlighting and/or formatting can help
to make the individual items stand out:
[x*y for x of range(XDIM)
if x&1
for y of range(YDIM)]
There may be syntactic alternatives that make it easier to
spot and separate the generators and filters. ES syntax
tweaking is notoriously tricky, but perhaps something like
[ x*y : x of range(XDIM); x&1; y of range(YDIM) ]
