ANN: PLT Scheme 301.12
Sorry about the lag in this announcement, still nothing is extremely different.
MzScheme and MrEd are now version 301.12 in the SVN repository trunk.
* Added `char-general-category’.
* Extended readtables to support a parser used where the default
reader parses a symbol or number.
* Changed the internal representation of some syntax information to
increase sharing across modules. This saves a little memory in
DrScheme, and a lot of space in “.zo” files.
Matthew also explains that char-general-category ” … returns a character’s Unicode general category, such as ‘lu (= Lu, uppercase letter) for #\A.”.
