[myhdl-list] toVerilog fails interactively

[Haitao Z. <ha...@gm...>]

This may be common knowledge but I may as well post it in case someone
else run into similiar problem:

toVerilog tries to find the instance name of what it is assigned to,
i.e. the lname in the following expression:
           lname = toVerilog(...)
It does this by inspecting the source file. When run interactively
some of the functions it calls fails because it can't get the info
from stdin. When running from a file (either a standalone script or
through execfile) it works fine.
