bad error message "defining function based on alias"

[Vincent Lefevre <vincent@xxxxxxxxxx>]

With zsh 5.9:

cventin% alias foo=true
cventin% foo() { }
zsh: defining function based on alias `foo'
zsh: parse error near `()'
cventin% alias bar=foo
cventin% bar() { }
zsh: defining function based on alias `foo'
zsh: parse error near `()'
cventin% unalias foo
cventin% bar() { }  
zsh: defining function based on alias `bar'
zsh: parse error near `()'

The second "zsh: defining function based on alias `foo'" should
really be "zsh: defining function based on alias `bar'".

And shouldn't one get only one (more accurate) error message?
The additional "parse error" is confusing.
