Tomas Rokicki created GROOVY-8079:
-------------------------------------

             Summary: Literal numeric constants cannot start with or end with a dot
                 Key: GROOVY-8079
                 URL: https://issues.apache.org/jira/browse/GROOVY-8079
             Project: Groovy
          Issue Type: Bug
          Components: Compiler
    Affects Versions: 2.4.8
         Environment: Windows, but probably generic
            Reporter: Tomas Rokicki
            Priority: Minor


Groovy prefers the . (dereference) operator over the decimal interpretation, but does not permit use of decimals that are conventional:

groovy:000> .3
groovysh_parse: 2: unexpected token: . @ line 2, column 1.
   .3
   ^

groovy:000> (.3)
groovysh_parse: 2: unexpected token: . @ line 2, column 2.
   (.3)
    ^

groovy:000> (3.)
groovysh_parse: 2: unexpected token: ) @ line 2, column 4.
   (3.)
      ^

groovy:000> -.3
groovysh_parse: 2: unexpected token: . @ line 2, column 2.
   -.3
    ^
