Function parse_paren_expr 

pub fn parse_paren_expr<P: Parser>(p: &mut P) -> ReportedResult<ParenElems>

Try to parse a parenthesized expression. This is a combination of a variety of rules from the VHDL grammar. Most notably, it combines the following:

• aggregate
• association_list
• suffix of slice_name
• suffix of indexed_name
• suffix of function_call

paren_expr := "(" { [ { expr }"|"+ "=>" ] expr }","+ ")"
