Re: [Xsb-development] Change to XSB

[Michael K. <ki...@cs...>]

.pl is also used for Perl, by the way.
I think it is bad to hard-wire .pl into the code.
It is never a good programming practice to use explicit constants scattered
out in the code.

One of my students who was an intern at Microsoft told me that his boss
warned the interns that if he sees any constant other than 0 or 1 in their
code -- they are fired. Although, apparently, this policy alone cannot fix
all MSs problems with the code, at least they are trying ... And so should we.
