question about for-loops on mappings

[janesser]

i am trying to get a for loop over a dict (not a list)

is there some best-practice function that would e.g. unfold dict.keys() to a visitable list ?

snapcraft.yaml.template:24:10:
  'Expression' object has no attribute 'visited':
   $_.epackages[$_.version][$_.name].keys()
Finished with errors.

thanks in advance

Iterating over arrays resulting of expressions has not been considered, unfortunately...

Can you submit a PR illustrating your expectation in test/samples? If it is not too complex, we might invest time to tackle this.
