[sv-ec] Associative array default value

Hi,

7.9.11 says,

"Associative array literals use the '{index:value} syntax with an optional default index. Like all other arrays, an associative array can be written one entry at a time, or the whole array contents can be replaced using an array literal.

For example:

// an associative array of strings indexed by 2-state integers,
// default is "hello".

string words [int] = '{default: "hello"};

// an associative array of 4-state integers indexed by strings, default is -1

integer tab [string] = '{"Peter":20, "Paul":22, "Mary":23, default:-1 };

If a default value is specified, then reading a nonexistent element shall yield the specified default value, and no warning shall be issued. Otherwise, the default initial value as described in Table 7-1 shall be returned.
Defining a default value shall not affect the operation of the associative array methods (see 7.9)"

Question: the examples only show the use of a default in an associative array initialization. If such an assignment is performed to an associative array later in the simulation, does it become a new default value, or does it have that effect only if specified at initialization?

In the implementations I tested, this assignment did change the default. I think the LRM should be explicit about this.

Thanks,
Shalom
