They do have the same function and are both implementation details.
The only reference to it I see in the ActionView documentation that is
not in a protected method for dealing with template compiled methods
is this:
<quote>
If you need to find out whether a certain local variable has been
assigned a value in a particular render call, you need to use the
following pattern:
<% if local_assigns.has_key? :headline %>
Headline: <%= headline %>
<% end %>
Testing using defined? headline will not work. This is an
implementation restriction.
</quote>
I am pretty sure this isn't true. I've tested using defined? in an
rhtml template and it worked fine for me. They are implemented as
normal local variables now so I don't see why you would need this.
ActionView in the semi-recent past was defining methods to simulate
local variables (as was Haml), possibly this was a work around.
Anyway, might be nice to change purely for consistency, but it's not
part of the public interface of ActionView. ActionView documentation
should probably be updated to remove that unnecessary pattern.
