Description

The wording in [exec.snd.expos] p14.2 (see https://eel.is/c++draft/exec#snd.expos-14.2) is written as follows:

  • Otherwise,
return Domain();

where Domain is the first of the following expressions that is well-formed and whose type is not void:

  • get_domain(get_env(sndr))
  • completion-domain<void>(sndr)
  • get_domain(env)
  • get_domain(get_scheduler(env))
  • default_domain()

However, since Domain is an expression, the statement return Domain(); looks like it's trying to invoke the result of the expression, which is probably not what was intended.

I suspect it should instead say "where Domain is the type of the first of the following expressions that is well-formed ...".
