combined functionality of ipython's %whos and pdb's next (without a resource heavy IDE)

[Benjamin J. Racine]

I am trying to combine the ability to move line-by-line through the code as is done with pdb's "next" function with ipython's ability to list all variables at once... without the use of a full-fledged IDE.

I am not seeing how this might be done.  Many thanks for your help...
