Assign var

[JesusKB]

I need a assign var function so much! I see this - https://github.com/mardix/ThickMustache, but is old.
My framework can't work without assign var correctly. Please, give me a example how to add this feature.

Yes, this would be nice. Maybe assign_var_array is nice thing too. (Working like method arrayiterator)
