Added module code to Modules cache - but (still) getting 'Module XYZ' not found

Can't you confuse the IDE, to work around this? I thought you could do this and the IDE would let it through (I remember doing something like this before the IDE could load modules from local filesystem)...

var x="ABC";
require(x).connect(...);

In an ideal world, I think this should pop up a dialog "Module XYZ not found, send anyway?" with a check box to not show it again, but I would consider this pretty unimportant, since it's such an exotic use case, and there's a workaround.
