It's worth remembering that Erlang syntax is based on Prolog syntax,
and Prolog has always had PL/I-style /*...*/ comments. Somewhere on
the way to Erlang, such comments were deliberately *removed* from
/* ... */ comments have no known advantages over % comments;
with adequate editing tools it is equally easy to "comment out"
or "comment in" a region either way and they are equally easy
to type or reformat.
However, /* ... */ comments come with several risks, which can
be ameliorated by syntax colouring to be sure, but not all programmers
