[/SOURCE]using static var from function outside the functionbody
Author
Im using a static variable from a funktion outside the funktion.
Is there any danger doing this?
Dangers:
1) Obvious: Don't try and delete the returned value. Return a reference instead to indicate the function owns it.
2) Pernicious: Global data can destroy your design.
