Now, I agree it’s a big task, and one I’d rather avoid 2 months before 2.0. >> I’m in favor of ‘.go’ alongside ‘.scm’: that’s what happens with >> .elc/.el and .pyc/.py and it had been the plan from 1.9.0 until >> recently. > > For python, pyc files are in $libdir, for exactly this reason. Out of curiosity, are .pyc endianness- and word-size-sensitive? What about .elc? Guile itself currently installs ‘.go’ under $pkgdatadir. That would need to be changed to $pkglibdir/1.9, right? Also we now have $GUILE_LOAD_PATH and $GUILE_LOAD_COMPILED_PATH. Should we also have an equivalent to ‘-L’? Thanks, Ludo’.
