[Discuss-gnuradio] gr.hier_block2 in Python

[Marcus D. Leech]

So, I've been thinking about my ideas with respect to a "universal" 
source block that would allow runtime selection of FCD, UHD, or RTL-SDR
  blocks.

Is it possible to specify a source block purely in Python using 
gr.hier_block2?

If so, then the Python code could construct and plug in the appropriate 
actual source block "under the covers", based on some
  yet-to-be-determined syntax at runtime.  It could even use the 
conditional-importing goo in Python to decide whether you have
  any/all of the appropriate hardware-specific support configured in 
the build.
