This transformation should not be a part of interpose function,
interpose does know nothing about elements type and doesn't have to
know.  This addition is semantically incorrect and also contradictionary
to docstring.  It also breaks downstream channels.

The version of change in master is different, it doesn't even check
element type.

I'm strongly against this change.  If it necessary to make
transformation of elements of the list it should be done outside of
interpose.
