What do you mean by 'proper'? Eg, the typical example for something
where anything but enabling direct access to 'a package variable'
makes little sense would be some kind of 'debugging level' variable
which can be used to control the amount of diagnostics a program will
print: That's typically modified in one or two location (the code
which deal with command-line arguments and something like a signal
handler which can be used to change the value for a running program)
and read-only referenced from everywhere else in the code. This really
depends on the purpose of the variable.
