I have a strong use case for render_to_string in views.
This is in the context of a facebook app, but I can imagine a lot of
scenarios where this might occur:
Consider:
<fb:request-form content="<%= h render_to_string :partial =>
'invite_text' %>">
The invite text is full of HTML that needs to have entities encoded so
it can be stored in an attribute.
It seems to me this ought to be supported out of the box, but what do
people think. Plugin?
