.. index:: entry doesn't work with styles

Hi:

I'm trying to use the following:

.. index:: cos()

or even better:

.. index:: :php:func:cos()

Because I want to get the index entry in monospace font in the index.

However, it doesn't work, because the index entry shows literally as cos() or :php:func:cos().

Is there a way to do this?

Thanks!

The index directive can describe punctuations also. So it does not parse mark ups. So it would be nice if we can add styling property like :class: option.
@shimizukawa do you have any idea for this?
