Change of behavior for `define*'?

[Patrick McCarty]

Hi,

I'm trying to get LilyPond compiling with Guile git (commit 7cd554),
and I'm running into a problem that I don't see documented in NEWS.

With Guile 1.8.7, this code is valid:

  guile> (use-modules (ice-9 optargs))
  guile> (define* a 1)
  guile> a
  1

But with git, I get the following:

  scheme@(guile-user)> (define* a 1)
  Throw to key `syntax-error':
  ERROR: In procedure sc-expand:
  ERROR: source expression failed to match any pattern in (define* a 1)


Is this an intentional change of behavior in Guile, or is it a bug?

Thanks in advance,
-Patrick
