Re: should fset 'symbol get an undefined function warning?

[Richard Stallman]

    The warning "the function `my-fset-test' is not known to be defined"
    is generated when compiling:

    (fset 'my-fset-test 'foo)
    (my-fset-test)

If you use `fset' it means that you are playing around with the
symbol's definition.  So it seems like a mistake to assume anything
about it.  Normally the first arg of `fset' is not a quoted constant
anyway.

If you want to make an alias that the compiler will know about, use
`defalias'.
