Re: Running Compiled Guile Objects

[Nala Ginrut <nalaginrut@gmail.com>]

It's unnecessary to manually load .go files. You can pre-compile .scm to
.go and install to the compiled-load-path. And put .scm to load-path, if
your path is correct, and if the .scm is no newer than .go, Guile will
automatically load .go directly without auto-compilation.

BTW, I saw some Guile project didn't install .go to correct path. Even if
Makefile compiled .go and installed, the program will trap to
auto-compilation for the first time.
However, it's the matter of tweak the install path, rather than manually
load .go.

Best regards.
