Subject: Strings and string parameters

In the AMS committee this morning, it was requested
that one be able to initialize a string using a
string parameter.  This seems to be missing from SV,
which says:

  The syntax to declare a string variable is as follows:
    string variable_name [= initial_value];
  where variable_name is a valid identifier and the
  optional initial_value can be a string literal or the
  value "" for an empty string.

It says nothing about a string parameter, nor, in fact,
other string variables:
    string str1 = "hi";
    string str2 = str1;

I think this would have to go through the SV-BC, right?

Since "string" is a data_type, I presume one can declare
a string parameter in SV, though I don't see any examples;
it should probably be made clear somewhere that a string
literal default value for a string parameter is also run
through the conversion process (stripping \0).
