Summary

0005361: BNF does not allow templates in return statements

Description

It is possible to define TTCN-3 functions that return a template. However the current definition for return statements in the BNF does not allow returning a template:

  ReturnStatement ::= ReturnKeyword [Expression]

It should be replaced with the following:

  ReturnStatement ::= ReturnKeyword [Expression | TemplateBody]
  /* STATIC SEMANTICS - The Expression shall evaluate to an explicit value of a type compatible with the return type for functions returning a value and shall evaluate to an explicit value, template (literal or a template instance) or a matching mechanism compatible with the return type for functions returning a template. */

Note that section 19.10 should be updated as well.

(0009100) Ina Schieferdecker (reporter) 08-12-2009 16:15 edited on: 08-12-2009 16:27	As proposed - just rewording the comment: Expression shall evaluate to a value of a type compatible with the return type for functions returning a value. It shall evaluate to a value, template (literal or template instance), or a matching mechanism compatible with the return type for functions returning a template.
