The Wikipedia article corresponds with my experience using them:
The problem is to keep track of what part of the program is changing
which global under what circumstances. Certain globals, such as the
session description, are unavoidable. For other shared information, I
find that defining a singleton object is a better tool because I can
more easily identify who is using it.

Are there times when using these are considered good practice or would good architecture always provide an alternate solution (such as passing the variable into the function)?
