package.loaders -> Is modifying it supported?

[Shaun <delius@...>]

Hi All,

I notice that Lua 5.1 introduces a new table, package.loaders that 
includes a series of functions that are invoked trying to satisfy a 
'require' statement.

Is it this table supported? Is it ok to modify it (from the code that 
embeds LUA) to introduce generic loaders that should be executed before 
the existing ones?

Thanks,
Shaun
