tokens

This feature would be really useful. Also, tokens to get the current url arguments would be a beneficial addition (e.g. a non-PHP way of getting at the URL arguments), especially if they failed gracefully when the argument isn't present (i.e. just ignore it).

I do not plan to implement tokens myself, I welcome patches, but I feel this is not urgent because:
1) There is already a CCK field module (View Field) which accepts tokens as arguments to display views
2) You can use PHP to achieve the same effect.

It's urgent for me :) but I'm happy to try to create a patch, except I think my patch would be for token. I have another post http://drupal.org/node/334634 asking for some help figuring out how to add new tokens.

1) I'm using the View Field module to create a view of type B (view B) embedded in type A, displayed as a view of multiple A (view A), e.g., A1, A1.B1, A1.B2; A2, A2.B1, A2.B2, A2.B3; etc. The problem in this situation is if I provide URL arguments to view A, those arguments don't seem to be available to view B which is embedded in each row of the type As being displayed. There are no tokens I am aware of currently to support URL arguments and AFAIK I can't put PHP into the arguments to view field (it just uses whatever tokens are defined by installed modules, in my case token and CCK).

2) I have not been able to implement my scenario in PHP. I can get the embedded view to show up in the individual node display for A, but as soon as I put A into a view, view B doesn't have access to the NID of A (instead it is getting the NID of the page displaying the view as best as I can tell). It seems like there might be a work-around by using PHP in a theme, but I'd like a simpler solution. It doesn't seem right to me that I'd need to create a custom PHP file for every theme.

In any case, it seems to me like view field is the right module for my specific situation, and I just need to sort out how to add arg0, arg1, ... argn to the token module.
