GString map key
Reports statements which use a groovy.lang.GString object as a key to map. In general GString objects are mutable and probably should not be used as keys. Also, a GString entry cannot be accessed with a java.lang.String object with same value.
Example:
def map = [:]
def key = 'foo'
map << ["${key}": 'bar']
assert map[key] == null // confusing 'true' result of comparison
