provide it a real, it interprets as a single radius. Provide two packaged into a complex, and it interprets as two real values.

No, I don't think it would break the ARC command nor cause backward compatibility issues. The reason I suggested a new command is because a complex number can be written as either a+b*i or (a,b), with the latter being fairly common (fewer keystrokes). In the past, we have seen far too many issues with commas (number separator vs digit separator or , vs ; for separators, etc). With a new command, you can specify whatever you want for the arguments (so as to avoid using a complex number). I don't know the inner workings of the parser, so perhaps a simple switch in object type would suffice to add this feature to the existing ARC command.
