John Wagenleitner commented on GROOVY-8036:
-------------------------------------------

I can't replicate that error (NPE):

{code}
$ cat groovy8036.groovy 
int a = 5
[1..a].each
{ -> println "qwerty" }
{code}

{code}
$ ./groovy-2.4.7/bin/groovy groovy8036.groovy
Caught: groovy.lang.MissingMethodException: No signature of method: groovy8036$_run_closure1.doCall() is applicable for argument types: (groovy.lang.IntRange) values: [1..5]
Possible solutions: doCall(), findAll(), findAll(), isCase(java.lang.Object), isCase(java.lang.Object)

> With code like this:
> int a = 5

> the compiler throws an NPE. OK, this is incorrect code since it is missing a value before '->', but this should preferably produce an error message and not an NPE :-)
