Re: W3m.el and Emacspeak (non-member post)
Nothing religious --here is the practical problem that macros cause
systems like emacspeak
that try to use services offered by other packages while
Consider for instance 'w3m-anchor --
It's useful to call this from inside emacspeak code to get the anchor
information and speak it.
However, since it is a macro,
byte-compiling the emacspeak-w3m module will give errors unless w3m
and all its modules are loaded when compilation happens.
I cannot setup emacspeak to load w3m at compile time since w3m may be
installed in some non-standard place by the user.
Given that emacs lisp has defsubst which inlines the code,
there is no reason to use defmacro for this purpose --macros can (and
should be) used to create special forms where needed.
