IIUC, the OP used this command line after a booststrap:

Thus the comment about the possibility of adding a check for non-existent switches.
Providing some options that require no "-', some that require "-", and some that require "--" may make sense from an internal perspective, but this is terribly confusing to the user. So the user often makes mistakes. To have the mistakes silently ignored makes it difficult or impossible for the ordinary user.
Ah, yes, we've had that come up before.. Unfortunately the "--" options are an open set. So it's rather hard to actually detect when those are non-existent.
Is there some way that we could mark options as used? Could we require everything to go through the options module instead of doing a raw match against ARGV? At least, would it be reasonable to warn about arguments that would look like properties if they didn't have the --? In Christ, Steven Watanabe
