Gauche 0.8.8

From the Gauche web page:

Gauche is an R5RS Scheme implementation developed to be a handy script interpreter, which allows programmers and system administrators to write small to large scripts for their daily chores. Quick startup, built-in system interface, native multilingual support are some of my goals.

To reproduce my results on Ubuntu Gutsy Gibbon, install Gauche with

sudo apt-get install gauche

and run the interpreter with

gosh -i -fcase-fold 2>&1

Gauche makes the following choices:

Allows the null combination, (), which returns the empty list. (more)
Allows forcing non-promises. (more)
Evaluates unquoted vectors to themselves. (more)
Allows division by inexact zero. (more)
Allows inexact division by zero. (more)
Allows division by exact zero. (more)
Supports arbitrary precision literal integers. (more)
Supports arbitrary precision computed integers. (more)
Supports the literal syntax for rational numbers (e.g. 1/2 is the literal number one half). (more)
Supports the literal syntax for complex numbers (e.g. 1+i is the complex number with real and imaginary parts both 1). (more)
Supports nontrivial exact rational numbers (e.g. (/ 1 3) produces an exact one third, not a floating point approximation). (more)
Defines the denominator of an inexact number to be inexactly 1.0. (more)
Does not define the procedure 'transcript-on'. (more)
Does not define the procedure 'transcript-off'. (more)
Does not define the procedure 'rationalize'. (more)
