[racket] using new (~a ...) form for errors: minor irritation?

I'm really enjoying the new (~a ...) formatting forms, but I'm wondering about a workaround for this minor irritation:

When I call (error...), I typically use the form that includes the function name. However, this form treats its second argument as a format string, not as a message. This means that if I want to use this form, I have to write:

(error 'my-proc "~a" (~a "You messed up, "name"."))

I suppose I could use the more concise:

(error (~a "my-proc: You messed up,"name"."))

... but I feel like I'm losing information by gluing the function name into the message prematurely.

Am I missing something obvious? Aside from just using raise-argument-error more often?
