Setting the behavior of something is a one time thing. Start Using is something

ummmmm - not 100% "no effect".
If you have a 'librarystack' handler it will be run each time you 'start
using' the stack, and therefore if it does something without checking
for having been already run, you can get unexpected effects. (For
example, if your librarystack handler was to explicitly set some
variable to empty then that would overwrite (i.e. lose) any value set
since the previous occurrence.
Like others have said, I use a folder (I call it Libraries) with the 'My
Livecode' folder to hold all my libraries (and I make sure they can be
'start using'ed multiple times. If I have a library which depends on
other libraries, I give it a librarystack handler which (among other
things) will 'start using' any libraries it requires.
