One of the things criticised in the blog entry that we've been responding to was
that
{ok,Foo} = bar(...),
{ok,Foo} = ugh(...)
is too easy to write (when you really meant, say, Foo0, Foo1).
This is a well defined part of the language, and it would not be a good idea to
ban it. But how about an optional style warning (and we really need
-warn(on | off, [warning...])
directives) whenever a bound variable appears in a pattern on the left of "="?
