[issue26156] Bad name into power operator syntax

[Zachary Ware]

Zachary Ware added the comment:

I agree that what is currently in the docs is technically correct.  The section on the power operator:

   power ::=  await ["**" u_expr]

should be read as:

   power ::=  (["await"] primary) ["**" u_expr]

just as the definition of 'u_expr' below should be read as:

   u_expr ::=  (await ["**" u_expr]) | "-" u_expr | "+" u_expr | "~" u_expr

and 'await' should be read as:

   await ::= ["await"] (atom | attributeref | subscription | slicing | call)

Each definition builds upon previous ones.

However, it is confusing.  Could a name other than "await" be used, since "await" is easily confused with the keyword await?
