Extending operator record

[modelica-trac-importer]

Reported by jmattsson on 20 May 2014 14:50 UTC
The table in section 4.6 of the spec contains:

• You are allowed to extend from an operator record as a short class definition (with certain restrictions).
• You are not allowed to extend from any enclosing scope of an operator or operator function.
• operator and operator function are only allowed inside operator record.
  Together this gives that you are only allowed to extend from an operator record (as per the first point) if it doesn't contain any operator and operator function. The rule about enclosing scopes needs to be amended.

(Also, the item in the table for operator refers to "Section Chapter 14".)

Ok, as I see the "operator" and "operator function" the rule about no extend should exclude the special case for "operator record".

Due to #1459 the new text would be:

operator:
Similar to package; but may only contain declarations of functions. May only be placed in an operator record.

operator function:
Shorthand for an operator with exactly one function; same restriction as function class and in addition may only be placed in an operator record.

(Since "operator" is placed in "operator record" the enclosing scope is the operator record, so no need to add any additional restriction for extends.)

Spec group:
Agree and also change "Section Chapter 14" to "Chapter 14".
