Description

People have reported that it can be prohibitively slow to call SET-MACRO-CHARACTER on all potential Unicode characters.

I'm not surprised by this, but I'm not sure that there's a good reason to make it impractical for someone who wants to do this to do so, either.

changing the data structures that CCL uses to associate characters with functions can affect things like SET-SYNTAX-FROM-CHAR and COPY-READTABLE as well as SET-MACRO-CHARACTER and (poossibly) SET-DISPATCH-MACRO-CHARACTER.

(In [16442]) Use sparse-vectors for reader-macros. seems to scale better. Fixes ticket:1282 in the trunk.

Back to work.
