If 'exists' was vectorised in its first argument then there wouldn't be 
a need to use lapply with it, would there? I'm guessing the original 
problem stems from something like:

  got = exists(c("X","Y","Z"))

  not working and the user thinking lapply would do nicely...

  How to vectorise it without introducing another existing variable is 
another problem...
