My experience is that C code that conforms to its standard is /way/ more portable than Common Lisp code that conforms to its standard. Lest there be any confusion about where I stand on this: /it pisses me off/ that Common Lisp system vendors have not just moved past the point where /everyone/ faithfully implements the standard. I have given up reporting conformance bugs, since conforming to the specification might break some paying customer's code. There are enough gratuitous incompatibilities between the Common Lisp systems and enough unimplemented standard behavior that you cannot program according to the specification and expect it to behave correctly. You must in effect always program to the particular implementation. Some vendors actually consider this a feature and argue that you have to program to the particular implementation, anyway, which does nothing but piss me off further. It is like arguing that you might as well break some laws because you cannot have laws for everything. Playing with a particular Common Lisp system is fun, but playing with several is not fun, as it forces me to be conscious of a large number of highly irrelevant minor issues, which is the exact opposite of the purpose of a standard. -- Erik Naggum, Oslo, Norway Act from reason, and failure makes you rethink and study harder.
