groovy的保留字：

abstract

as assert boolean break byte case catch char class const continue def default do double else enum extends false final finally float for goto if implements import in instanceof int interface long native new null package private protected public return short static strictfp super switch synchronized this threadsafe throw throws transient true try void volatile while

groovy中的修饰符：

abstract, final, native, private, protected, public, static, strictfp, synchronized, threadsafe, transient, volatile

这些修饰符和java中的是一样的。

类型申明

class, enum, interface

Property names

as, catch, class, def, default, do, else, finally, for, goto, if, in, static, switch, try, while
