 '<<' found (in your regexp) before '<'

 actually yes (it's like a P language)

 here your regexp

pigeon% ruby -rjj -e '/\\>|\\<|<<|>>|<|>/.dump'
Regexp `\\>|\\<|<<|>>|<|>'
  0     on_failure_jump         ==>   3
  1     exactn "\>" (2)
  2     jump_past_alt           ==>   5
  3     on_failure_jump         ==>   6
  4     exactn "\<" (2)
  5     jump_past_alt           ==>   8
  6     on_failure_jump         ==>   9
  7     exactn "<<" (2)

 16     end
