If 'the typing argument' isn't the main issue, _what_is_?  That lots of
implementations can easily support REQUIRE-EXTENSION?  Even _more_ can
support SRFI 7.  That it's an unquestionable existing mechanism?  SRFI
15, FLUID-LET, was also a pretty widely used mechanism that wasn't
questioned by the author...but notice that he later withdrew it,
because the mechanism was inherently flawed, whereas the intent of the
mechanism, dynamic environment manipulation, was not: thus SRFI 39 (I
still disagree with SRFI 39's design, but it's _much_ better than SRFI
15's.)
