我正在尝试从
http://groovy.codehaus.org/JN2515-Closures开始尝试Groovy闭包递归示例.
我将片段保存在一个名为recursionTest.groovy的文件中并将其加载到shell中,但我得到了“没有签名方法错误”：
// recursionTest.groovy
def results = [];
{ a,b ->
results << a
a<10 && call(b,a+b)
}(1,1)
assert results == [1,1,2,3,5,8,13]
groovy:000> load recursionTest.groovy
===> []
ERROR groovy.lang.MissingMethodException:
No signature of method: java.lang.Boolean.call() is applicable for argument types: (groovysh_evaluate$_run_closure1) values: [groovysh_evaluate$_run_closure1@6b7599cc]

at groovysh_evaluate.run (groovysh_evaluate:1)

这是怎么回事？
