R help - Oct 2009 - how do you know which functions are being debugged?

This is kind of a dumb question:  I know you can use isdebugged() to find
out if a specific function is flagged for debugging, but is there a way to
list all the functions that are flagged for debugging?
Thanks,
Andrew

list all objects first; use a loop (explicitly or not) to check
whether (1) your objects are functions (2) functions are debugged

   f
TRUE

    f
FALSE

No, R doesn't keep any master list, it sets a flag in each one.  So you 
could iterate over all visible objects to find the ones that have the 
flag set (and this is quite slow, there are a lot of places to look), 
but there would always be the chance that one was hiding somewhere you 
didn't look.
