Subject: bug#68030: 29.1; (elisp) `pcase Macro' Reformulation with `pcase' example
Date: Mon, 25 Dec 2023 16:41:22 +0000 [thread overview]
Message-ID: <SJ0PR10MB54885D3E1842181D8CD64F95F399A@SJ0PR10MB5488.namprd10.prod.outlook.com> (raw)
We shouldn't try to introduce (and perhaps even motivate) the use of
`pcase' for such a "simple matching task". The `pcase' version is
many times more complex than the simple `if' version with a
single-sexp THEN and a single-sexp ELSE.
Even if the aim is to present `or', `and', `pred' and `app', a better
example should be used - something where it really _helps_ to use those
subpatterns. In the example chosen they just add noise.
[Not part of this bug report, but you might also want to move the whole
`Caveats for SYMBOL in Sequencing Patterns' to a separate node (with
`pcase' somewhere in the node name).]
