Declaring reusable variables

[OskarPersson]

Is there something similar to Django's with tag to store result of complex or expensive methods for use in the template multiple times?

Not really, unles you count @if let ..., @match ..., or function / template calls.

It has been suggested before, so maybe it is a good idea. I guess there could be an @let template tag similar to @if let, but with an irrefutable pattern (you can actually use @if let variable = expression { ... }, but rustc will give you a warning about the "irrefutable if-let pattern").
