In GNU Radio's 'block' terminology, you will *never* call another block from
within one block's work function. You always connect the output of one block
the input of the next.
What exactly are you trying to do? Are you simply trying to outsource some
signal processing code out of your block?
We do this quite a lot, but then the object we call from the work function is
not a GNU Radio block, but rather a generic object. Of course, you can include
any Python module or object into your own Python blocks.
Or are you trying to call another, existing GNU Radio block? In this case, you
might want to think about splitting your block up such that you can connect
your block and existing blocks through the regular mechanism (i.e.
top_block.connect()).

Perhaps a hier block will solve your problem?
