Branch: MAIN
Changes since 1.5: +4 -1
lines
1. load_exec(FileName) : load and execute FileName. It can be used for
demand loading.
Caution : load_exec() cannot be nested. load() should be used within
a load_exec() execution.
XXX : there is a bug on printing of evaluted value containing load_exec().
2. Arithimetics of quoted objects has been implemented.
