Am curious about your use case? Why peek at something
that could be gone by the time you want to use it.
 val = q.peek()
 if something_i_want(val):
 v2 = q.get() # this could be different than val
Wouldn't it be better to just get() the value and return if you don't
need it?
 val = q.peek()
 if not something_i_want(val):
 q.put(val)
