Re: [sv-bc] Typing of parameter assignments

According to the P1800 LRM, the list of assignment-like contexts is
exhaustive. "No other contexts shall be considered assignment-like
contexts."  So the LRM is unambiguous that an assignment pattern is not
legal as the right-hand side of a defparam.

However, as Gord says, "assignment-like context" is only relevant to
assignment patterns.  For example, although the argument of a static
cast is evaluated in the context of an assignment to a variable of the
result type, an assignment pattern is not legal as the argument of a
static cast, because a static cast is not an "assignment-like context".
