This is a typical question raised by many "newbies." Search the
archives of this newsgroups and you'll find similar ideas several
times. The short answer (IMHO) is that it can be done but once you
grok what's cool about Lisp you don't want to do it anymore. It's a
waste of time.
You might also want to look at Dylan for one example of a "Lisp++."

Yes, this is not a Lisp-specific question, it applies to all
programming languages. The usual answer is: RTFM.
For Common Lisp there's an ANSI standard and an online version is
available here:
<http://www.lispworks.com/documentation/HyperSpec/Front/index.htm>
Plus, your specific Lisp implementation will usually offer much more
functions than those that are specified by the standard. They'll also
have manuals. Here are some examples:
<http://www.lispworks.com/documentation/index.html>
<http://franz.com/support/documentation/>
<http://www.cons.org/cmucl/doc/index.html>
<http://www.sbcl.org/manual/>

And so on and so on...

Nonsense!
To the OP, your respondents are the ones who need to RTFM. Check out
apropos. In AllegroCL 7:

Note that you can do (apropos 'rand) and find anything with "rand" in
the symbol name. A couple of reasonable guesses will turn up most of
what you are looking for, if it is there. If that does not work, do try
the hyperspec since some functions are named surprisingly.

I've gotten in the habit of using a string for apropos. When using a
symbol, it gets interned, and is immediately appears in the results of
apropos.

To avoid that, my habit is to use keywords. Yes, they *also* get
interned and immediately appear in the results of the APROPOS,
but those keywords don't pollute the package I'm in at the time,
and thus don't interfere if I want to import one of the other results.
[And who cares about polluting the keyword package, anyway...]

Right. We also have the google facility built into many of our IDEs.

Yes, it'll also turn up lots of internal functions and odd symbols.
Perhaps
CL-USER> (apropos 'rand 'common-lisp)
RANDOM-STATE-P (fbound)
RANDOM-STATE
*RANDOM-STATE* (bound)
RANDOM (fbound)
ARITHMETIC-ERROR-OPERANDS (fbound)
MAKE-RANDOM-STATE (fbound)
; No value

Also I find most of the newbies don't use the permuted symbol index in
the hyperspec. A shame really:

(Edi may have pointed this out already, I am too lazy to check).

I am spoiled, I have the AllegroCL apropos /dialog/ which lets me poke
first the external-only checkbox and then, if that is not enough (unlike
this case), the functions-only checkbox. Hellasweet.

good idea. One could take the other suggestion and add to one's image:
(defun apropos-cl (whatever)
(apropos (string whatever) 'common-lisp))
...while learning CL. Adding keywords for fn-only-p, class-only-p,
exported-only-p left as an exercise (hint: (apropos 'apropos))
