Well I meant without doing that; i.e. someone somewhere earlier in the
program already did that pcall() and it failed and now I'm trying to
load the module a second time and want to know what went wrong.
Anyway, I guess the solution should have been obvious: just set
package.loaded.foo = nil and require() will throw the original error
again.
