Hi Larry,
TLDR: why `=>` rather than `as`?
As a userland developer I like what this is trying to achieve. I'm not
knowledgeable enough about the internals to comment on the finer details or
their ramifications - I just have a bike shedding suggestion/question which
seemed glaring to me so I wonder if it's because of an ambiguous syntax or some
other issue?
The `=>` symbol seems odd to me, given how it's used elsewhere (generally as an
indicator of a key/value pair, whether in an array or match block) and how
generators/iterables are used elsewhere (ie foreach as)
Your example is:
using (file_for_write('file.txt') => $fp) {
Whereas to my eye this seems like a much more obvious choice:
using (file_for_write('file.txt') as $fp) {
Anyway, just a thought.
Cheers
Stephen
