Paul King commented on GROOVY-8602:
---
Reducing priority. The only place map indexing is allowed is immediately after
a class constant, e.g.:
{code}
assert Date[year: 118, month: 8, date: 3].day == 1
{code}
I don't see a lot of value in supporting this:
{code}
assert Date?[year: 118, month: 8, date: 3].day == 1
{code}
If we supported using a class variable, I could see the value, e.g.:
{code}
def d = Date
assert d[year: 118, month: 8, date: 3].day == 1 // No map entry allowed at this
place
{code}
But we don't support this. You could perhaps argue for a slightly better error
message in this case.
