* Added the primitive (environ):
...
returns an alist of (string x string) as obtained from the
system environ.
* Added the primitive env:
(env "key") retrieves the env value associated with key
(env "key" "val") sets the env value assocuated with key to val
(env "key" "val" overwrite?) same as above but it does not
overwrite an existing value of overwrite? is #f.

Pretty-printed gensyms:
...
* print-gensym now accepts the symbol "pretty" as a valid
argument.
* The writer prints #:pretty-name if the print-gensym value
is |pretty|.
* The reader accepts #:id as a valid syntax. The result is
a fresh gensym with id as a pretty-name.
2006-12-25 11:33:03 +03:00

Tokenize now recognizes gensym syntax:
...
#{id0} => a fresh gensym with pretty-string id0
#{id0 id1} => an interned gensym with pretty-string id0
and unique-string id1.
id0 and id1 can have any identifier syntax including bar-quoted ids.
any number of whitespaces can be placed around id0 and id1.

Actually, the profiling times show that memory-based tests can be
...
performed at around 3 secs per 1 billion checks (about 6 times
slower than register-based counters).
2006-12-21 16:32:45 +03:00

Profiling timing shows that we can do interrupt checks with cost:
...
* about 2.0 secs per 1 billion checks if the counter is kept in memory
* about 0.5 secs per 1 billion checks if the counter is kept in register.
2006-12-21 16:22:07 +03:00

dropped. Dropped files are closed before new files are opened.
