For pointer or reference, the following is current behavior:
{code:groovy}
@groovy.transform.TypeChecked
void test7859() {
def x = 'abc'. // STC: Cannot find matching method java.lang.String#bar
x = String. // instance method closure that requires String as first
argument
x = String. // instance extension method closure that requires String as
first argument
}
{code}

I also found that {{String.}} (for example) is not usable.
{code}
assert ['ABC','XYZ'].collect(String.) == ['abc','xyz']
groovy.lang.MissingMethodException: No signature of method:
java.lang.String.toLowerCase() is applicable for argument types:
(java.lang.String) values: [ABC]
Possible solutions: toLowerCase(), toLowerCase(java.util.Locale),
toUpperCase(), toUpperCase(java.util.Locale)
at Script1.run(Script1.groovy:1)
{code}
Should I file a separate bug report for this?

The corresponding method reference equivalents using the Parrot parser suffer
from the same errors:
{code}
x = 'abc'::bar
x = String::length
x = String::size
{code}
This is to be expected given the current implementation.
