doc/ref/spec: harmonize list and struct comprehension

- list comprehensions are removed in favor allowing
  (front-style) comprehensions as elements.

- aliases are replaced with top-level let clauses.

- the original alias syntax is freed up to possibly serve
  as an alias for embedded values in the future.

- list elements now may be aliased.

- most keywords can now be used as identifiers and
  references.

At some point we should also generalize structs to always
except emit values, which would make this feature even
more orthogonal.

Closes #112
Issue #339
