> Evaluating
> {code}
> (1..3)[*0..2]
> {code}
> throws: {{BUG! exception in phase 'class generation' in source unit 'ConsoleScript42' SpreadExpression should not be visited here}}
> It works fine if I manually call {{getAt}}:
> {code}
> (1..3).getAt([*0..2]) // [1, 2, 3]
> {code}
> It also works if I add something besides the spread:
> {code}
> (1..3)[*0..2, 2] // [1, 2, 3, 3]
> {code}
> as shown in the Ranges and List-Slicing section of [Getting Started Guide > Collections|http://groovy.codehaus.org/JN1015-Collections].
> There are other SpreadExpression BUG!s, but I'm not sure if this bug is the same:
