In zsh-3.1.2, "echo foo.bar(:r)" prints out "foo", whether foo.bar
exists or not. In 3.1.2-zefram4, I get the error "zsh: no match" when
foo.bar doesn't exist.
Why has this been changed to only work with existing files? Is there
an option to override this?
Thanks,
Steve

This form was always documented as working only on the names of existing
files. In prior versions there was special-case code to allow modifiers
to be applied to any string without performing globbing, but in the
glob changes for 3.1.2-zefram4 I simplified things a bit by making this
actually invoke globbing. A side effect is that things like "foo(M)"
now work as expected.
You can get the effect you want -- applying modifiers to an arbitrary
string -- via parameter expansion: "echo ${${:-foo.bar}:r}" has always
been the correct way to do this.
