[erlang-questions] binary elements greater than 255

[Zvi]

Hi Igor,

I know that lately computer industry decided to switch from 6-bit to 8-bit
bytes :), which when unsigned can hold values in range 0..255. But this
wasn't my question. I asked, why Erlang compiler didn't return error, when
you give it input like <<256>>. I think it's a bug.
