Unhelpful error when using named arguments for non-optional parameters

[gramster]

I have this code:

void assert_that(arg1, [arg2=null, String arg3='']) {
  if (arg2 is Matcher) {
    _assert_match(actual:arg1, matcher:arg2, reason:arg3);
  } else {
    _assert_bool(assertion:arg1, reason:arg2);
  }
}

void _assert_match(actual, Matcher matcher, String reason) {
...}

When run, it throws an exception on the line where _assert_match is called. The exception is 'StaticResolutionException'.

A much better message would be 'inappropriate use of named arguments' or something similar. It would be better for this to occur before runtime too, so I'm putting it under the static analyzer.

There IS not warning for _assert_match() invocation in Editor/analyzer.
