02' WRX clutch/tranny problem

I'd like to hear some suggestion on a problem I just had today. 2002
WRX, manual transmission, 113K miles. Came home this afternoon and
while parking car, got it in the first gear, moved slightly forward
and turned the car off. The clutch pedal didn't move back to the
regular position. It remained stuck to the floor. I didn't want to
start the car again and just turned the key slightly on to find out if
the 'Check Engine' will remain lit and it did. At this point I don't
want to do anything and will probably call towing service to deliver
it straight to the repair shop. Any idea what could that be? Clutch or
some more serious tranny problem? Not sure if this is coincidence or
not, the tranny oil was flushed and changed just a couple of days ago.
The clutch itself was replaced @ 75K miles on the car and I didn't do
anything nasty with it, just regular driving. No signs of issues until
today. I'd like to get some ideas on possible cause before discussing
this with the mechanics (don't want to get ripped off).....BTW, these
are the same guys that flushed the tranny oil....

Thanks!

Thanks for a reply. Yes, the pedal was exactly as usual and there was
no any 'soft' feeling in the past few days. Everything normal. Didn't
notice anything unusual after fluid change. A real surprise, as I just
came back home after 40 miles drive when this happened. No trace of
problem noticed during the trip. I presume if it ran out (or was
running out) of hydraulic fluid somehow, that would be a gradual
process with an earlier sign. I see no leak though...I searched the
web in the meantime and found a similar problem that was referring
master/slave clutch cylinder...looks like a copycat problem by the
described symptoms.
