Hi Shlomi,

Let's say I have a module XYZ with a sub in it call ABC. I'd like to
print the source code of XYZ::ABC.
My reason for this is I accidentally overwrote a module with an older

I have code that looks like this:

Hello,
I have a programme for database backup / recovery / some other tasks
with several modes (e.g. ackup etc.) in wich a certain function is
called. In this function I do a SWITCH, depending on the mode that the
main programme is started with. In one of the cases of SWITCH (e.g.
