Re: stack level parameter

[GrayFace <sergroj@...>]

IMO, stack level parameter is a problem in 'error', not in getfenv/setfenv.
I think a solution to both is to have a way to mark current stack level 
as 'skip me'. It can be stored in CallInfo structure. Functions like 
pcall should set this flag.
