Assert() and Friends
This has been puzzling me for a while, now...
In Dylan code I've seen, there are no Assert()-style macros for
debugging that I could see. This surprized me, as a debugging library
could easily be implimented with two sets of macros, one for test builds
one for final builds, that defined:
define macro assert
{ assert( ?expression: ) }
=>{ if( ?expression ) break(); end if; }
end macro assert;
in the debug version, and:
define macro assert
{ assert( ?expression: ) }
=>{}
end macro assert;
in the final version. To select test or final, you'd include the
relevent .lid which would build the relevent version under the same
library and package name.
Is this a good or bad idea, and why haven't I seen it? Have I just not
looked at enough code? :-)
