One thing that could be done right now is to provide a BIF which
is equivalent to your bstring:chr(Char, Binary) function, i.e.
return the position of the first location of Char in Binary
(or 0 if Char was not found.)
Since the current bit syntax doesn't allow constructs like:
chr(S, C) when binary(S) ->
case S of
<_:Size/binary, C:8/char |_> ->
Size + 1;
then perhaps the string:str/2 function should also have a BIF
equivalent for binaries?
and, while we're at it, a binary:reverse(Binary) BIF would also
