Seeking recommendations / suggestions for use of library stacks.

[Alex Tweedly]

I'm starting to make more use of library stacks (partly because I'm 
trying to switch away from revIgniter to a CGI-based solution to allow 
me to do more work & debugging in the IDE).

And now I'm looking for best-practice and/or suggestions for how to use 
library stacks. The not-quite-obvious context is that if some other 
library is later put into use, and it has no librarystack handler, then 
the librarystack message can get through to my (already in use) library.

My naive approach (from non-LC background) was very simple :

all initialisation would be done in the librarystack handler

that handler would also set a script-local variable to avoid repeated 
initialisation

so something like

local sIHaveBeenInitialized
on librarystack
   if sIHaveBeenInitialized is empty then
     put the millisecs into sIHaveBeenInitialized
   else
      -- setup initial / default values, etc.
      ....
   end if
end librarystack

This is fine for subsequent usage of the library - however, it's not so 
convenient while working on the library. The problem then is that any 
changes made to the initialization won't take effect unless I either 
manually unset this script-local, or exit / re-enter the IDE.

I thought about adding a reset handler, e.g.

on library_reset
    put empty int sIHaveBeenInitialized
    pass library_reset
end library_reset

which would give me a quick, safe and easy way to reset any (all) 
libraries from the message box. But then I thought it felt like I was 
rediscovering a wheel - so I thought I'd ask on here :-)

Is there another easier / better way to handle this ?

Thanks
Alex.
