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?
