Description

The following one-liner script using multiple assignment crashes Groovy:

def (a,b) = [1,2]

I.e. when I type in console

groovy A.groovy

I get an error message:

Caught: BUG! exception in phase 'conversion' in source unit 'A.groovy'
org.codehaus.groovy.ast.expr.ArgumentListExpression cannot be cast to org.codehaus.groovy.ast.expr.VariableExpression

Interesting that the bug affects only Groovy 1.8.0 installed with Windows Installer. Groovy installed from ZIP works as expected.
