Description

​println 09​

This code will cause a NPE, because it will be evaluated as println 0 9, which is evaluated as println(0).9. This happens because the leading zero introduces an octal, but 09 is no octal. The parser no falsely accepts 0 as valid number and does not recognize that 09 is supposed to be a single number anymore.

The expected behaviour is a compile time failure.

Daniel, can we fix that in parrot?
