[jira] [Updated] (GROOVY-5773) Problem distinguishing !=~ and != ~ plus similiar ones

     [ https://issues.apache.org/jira/browse/GROOVY-5773?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric Milles updated GROOVY-5773:
--------------------------------
    Description: In Groovy if you see x==\~y and x == \~y you can can get a problem, because it is easy to oversee the space in between, changing the meaning of the compare. The problem is toped by x != \~y being the negation of x == \~y, but there is no negation for ==\~. This issue is therefore asking for a replacement of the operators ==\~ and =\~ in a way that allows the negation too and is still readable. For this no unary operator symbol should follow the equals if equals is kept.
