Without arguing for or against allowing a capture variable, IMO rather than syntax like match <expr> into <var>: it would be far better (and not require a new keyword) to write this as with <var> as match <expr>:

If you've commented and you're worried you haven't been heard, please=20 add your issue *concisely* to this new thread. Note that the following=20 issues are already open and will be responded to separately; please=20 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=20 mark a variable binding and '?' for a wildcard.)
We already have 'with' for contexts.
We already have patterns with 'as': - except expression "as" identifier ":" - "import" module "as" identifier - "with" expression "as" target
So I think this would be quite confusing.
