Description

Java supports == for equality primitive types. Right now == means identity in Groovy. This is so confusing when working with numbers in Groovy.

So lets use

= for assignment
== for equality of all objects in Groovy
=== for identity

Right now we're using := for equality and == for identity. So

:= turns to ==
== turns to ===
