I have a question...
When enhancing ⎕NA to allow .NET assembly access, why did you choose a generic term like "EXT" to define the interface type (in place of the old DLL terminology)? Wouldn't something like ASM or NET be a better (more specific and meaningful) notation? What if you come up with some other external interface type in the future and you can't use EXT to define that one at the same time?
