[erlang-questions] Bit String Comprehension Question

[David Mercer]

Why does the bit-string comprehension #133 below work whereas #134 is a
syntax error?

 

133> << <<X:N>> || {X,N} <- [{3,5}] >>.


<<3:5>>

134> << Bin || Bin <- [<<3:5>>] >>.         

* 1: syntax error before: '||'

 

Please advise.  Thank-you.
