"Was not one of scheme original goals to a have small and extendable language and let's it's users use the library they want ?" That's *exactly* what they're getting: a small, meticulously crafted kernel language, upon which you can build whatever you like!
Interested in avoiding the fragmentation of a thousand non-standard libraries that do more or less the same thing? Got you covered there, too! R7RS-Large is a portable set of libraries for your applications. Fragmentation, be gone!
From the summary, the high-profile libraries include "networking, threads, regular expressions, delimited continuations, URI handling, date and time parsing/arithmetic/formatting, hash tables, ambient environment access, file system directory access, gettext (i18n support), and pattern matching." Yeah, that's going to be bigger than Common Lisp. On the other hand -- and I say this as a CL user -- it's almost a little sad, given the side of the Common Lisp standard, that so many of those features are left unstandardized.
don't worry, The United States will take care of and protect you.
"Take care of..." has a darned scary second meaning which, unfortunately, I feel applies here.
Old programmers never die, they just hit account block limit.
