I've experimented with a feature and shipped it.
What if the load function could pass arguments to the loaded file?
I designed it like this.
1. Extra arguments in load get implicitly bound to a special variable
2. If all the forms (or compiled forms) in the file are are evaluated,
and terminate normally, load returns nil.
3. The loaded file can evaluate (return-from load) to prevent the
remaining forms from being evaluated. Control passes to load.
If (return-from load <value>) is specified, load will return
that value, otherwise nil.
This may seem like a trifling thing, of no consequence, but it's looking
like a "game changer". Loaded files can be functions now, and they can be
procedures that modify their behavior based on arguments. It's looking
very convenient for build scripting; doing the cruft around getting a
multi-component system constructed.
You can do a recursive load across a tree of files, while telling those
recursive loads to do different things: compile files, clean, ...
