The problem came up when I was testing some of my old code against the git master branch. With an addition of: (use-syntax (ice-9 syncase)) to the main script the test case works fine with the 1.8 releases, so I was surprised by the change of behavior. I though it had worked with 1.9.1 but I probably didn't try it. It definitely did not work in the last two 1.9 snapshots I made, where guile-lib is also broken. The error message complained about "indx" but not "dotimes", and I jumped to the (wrong) conclusion that it was a problem during macro expansion, due to changes in the syntax expansion code. Thanks again. -- Barry Fishman
