I think we are storing up trouble unless we
1) Allow arbitrary expressions after `case`, interpreted *as now*
2) Use *different* syntaxes, not legal in expressions, for
alternative matching values (i.e. not `|` or `or`) (NB
simply stacking with multiple `case` lines is one possibility)
templates such as `Point(x, 0)`
anything else particular to `match`
I am reminded of the special restrictions for decorator syntax, which
were eventually removed.

Everyone,
If you've commented and you're worried you haven't been heard, please
add your issue *concisely* to this new thread. Note that the following
issues are already open and will be responded to separately; please
don't bother commenting on these until we've done so:
- Alternative spellings for '|'
- Whether to add an 'else' clause (and how to indent it)
- A different token for wildcards instead of '_'
- What to do about the footgun of 'case foo' vs. 'case .foo'
(Note that the last two could be combined, e.g. '?foo' or 'foo?' to
mark a variable binding and '?' for a wildcard.)
