Changes since Guile 1.3.2:
* Changes to the stand-alone interpreter
** Debugger
An initial version of the Guile debugger written by Chris Hanson has
been added. The debugger is still under development but is included
in the distribution anyway since it is already quite useful.
Type
(debug)
after an error to enter the debugger. Type `help' inside the debugger
for a description of available commands.
If you prefer to have stack frames numbered and printed in
anti-chronological order and prefer up in the stack to be down on the
screen as is the case in gdb, you can put
(debug-enable 'backwards)
in your .guile startup file. (However, this means that Guile can't
use indentation to indicate stack level.)
The debugger is autoloaded into Guile at the first use.
** Further enhancements to backtraces
There is a new debug option `width' which controls the maximum width
on the screen of printed stack frames. Fancy printing parameters
("level" and "length" as in Common LISP) are adaptively adjusted for
each stack frame to give maximum information while still fitting
within the bounds. If the stack frame can't be made to fit by
adjusting parameters, it is simply cut off at the end. This is marked
with a `$'.
** Some modules are now only loaded when the repl is started
The modules (ice-9 debug), (ice-9 session), (ice-9 threads) and (ice-9
regex) are now loaded into (guile-user) only if the repl has been
started. The effect is that the startup time for scripts has been
reduced to 30% of what it was previously.
Correctly written scripts load the modules they require at the top of
the file and should not be affected by this change.
* Changes to Scheme functions and syntax
** Readline support has changed again.

Returns true iff OBJECT is a directory stream --- the sort of object
returned by `opendir'.
** New function: using-readline?
Return #t if readline is in use in the current repl.
* Changes to the scm_ interface
** The internal representation of subr's has changed
