Hello,

I am trying to write a completion function for my custom command,
which should offer different suggestions for positional arguments
after a long option with mandatory value.  I have a code which works as desired
when the option is given in "--option VALUE" format, but not if specified
as "--option=VALUE".  In the latter case the completion 
is the same as without any option.

Here is a reduced minimum example for a command "mycmd"
(for testing purpose mycmd can be a symlink to /bin/true):

# _mycmd ---------------------------------------------------------------------


#compdef mycmd

                                                             

_arguments : \

    - name \

    '--name=[name of a person]:person-name:()' \

    '1:letters:(a b c)' \

    - without-name \

    '*:digits:(1 2 3)' \

    ;                                             

# ----------------------------------------------------------------------------


The desired behavior is that command lines starting as either
"mycmd --name Alice "  and  "mycmd --name=Alice "
should offer argument suggestions a, b, c,
however the version with the equal sign completes 1, 2, 3,
as if completing without the --name option.
The completion context appears to be incorrect in that case (_ marks cursor position):

$ mycmd --name Alice _

tags in context :completion::complete:mycmd::

    name-argument-1  (_arguments _mycmd)


versus

$ mycmd --name=Alice _

tags in context :completion::complete:mycmd::

    without-name-argument-rest  (_arguments _mycmd)



Is this a bug or feature?
If feature, am I perhaps missing some special specification flag to make it work?

Thank you,

Pavol
