Both Jacl and Tcl Blend already use a class loader called TclClassLoader.
Is there a feature that you would like to add added to the TclClassLoader
or are you looking to bypass it completely? I do not really see anything
wrong with adding something to the TclClassLoader or replacing it
completely with something better. I really do not like the current design
because as a programmer, you need to use the TclClassLoader explicitly,
when this type of thing really should be done behind the scenes. I was
also planning on stripping out the "feature" of the Tcl Class Loader that
automatically looks inside .jar and .zip files that appear on the
env(TCL_CLASSPATH). This makes the "worst case" lookup time depend on
the number of .zip or .jar files on the file system, which is really
ugly. Perhaps we should add a env(TCL_JARPATH) var instead?
