Somewhere between 3.0.0 and 3.0.1-test3, my namedir function (can't
remember the attribution, sorry) stopped working:
# Shorten the current directory to a ~ name
# (Only works as a zsh function)
$1=$PWD
: ~$1
It used to name the current directory; now it outputs this error:
zsh: no such file or directory: tf=/vobs/devel/shared/hsd100/testfiles

This should be
eval $1=\$PWD
: ~$1

Thanks, but why is this necessary? Was the change in behavior intentional?

I would not say that it was intentional. I always thought that eval is
necessary for that. In addvars() there is an explicite singsub() call to
substitute the left-hand-side of an assignment which is now only used to
substitute the index of the assignment. The change was that the lexer
gives the assignment token only if a word of the form number=value or
name=value or name[index]=value appears in command position where name has
only alphanumeric characters and underscores and starts with a letter or an
underscore. This fixes problems with 1foo=bar assignments.
