This is actually why my currently preferred bike shed color is "use underscores for files containing code". Taking the time to figure out when you can or can't use underscores takes mental effort, but the only value it gives you is occasionally being able to avoid a combined key press. (Pressing shift and a key together is more effort and coordination than simply pressing two keys in sequence.) Simply using underscores all the time makes things simpler, so coders can focus on other things. I'm fine with using dashes instead of underscores for command-line parameters, because those are usually typed in a non-coding context. But creating, opening, or including files containing code is done primarily in a coding context, and so staying "in a programming language determined mindset" is a feature rather than a bug. I don't have super strong opinions either way. -George _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/mailman/listinfo/xen-devel
