Some time ago I noticed that on some Tcl installations it could take a
noticeable time to respond to 'package require' calls. SInce I write a
lot of Tcl in CGI scripts (yes, very retro), that sort of delay was
becoming irksome.
To that end I wrote an extension for 'package' which lets you build a
lookup table of packages and speeds up loading them very effectively.
It's built into a system I wrote called web-template and can be found
on freshmeat.
Happy new year!
