Agreed - but there also seems to be a trend at the moment to propose
punctuation-based syntax, with keyword-based alternatives being
rejected on the basis that keywords break backward compatibility
(because of existing use as variables). I'm not sure a Perl-like
destiny (where we pile up extra punctuation) is that much better. I'm
not in favour of this idea (it seems likely there will be too many odd
corner cases and exceptions) but I can understand the motivation
As you say, the real solution is of course to exercise restraint in
what new syntax gets added. But looking at the recent "what's new in
Python" docs, the reality is actually a lot more restrained than
reading python-ideas might imply - so I'm not sure things are as bad
as they initially seem.
