v0.4.2-alpha
[Fix][Impl] 为了消除类构造带来的语法歧义,同时保持实现简洁和括号省略的语法,自此版本,引入了 `new` 操作符
造成歧义的原方法:
if a == A{}
条件是 a == A,还是 a == A{} ?
因此,现在使用 new a_struct{}来构造类
[Opti] 相较于 Fig v0.4.1-alpha版本,release O3同编译条件下
Fib普通递归法性能提升 ~50%
具体方式:
增加了小整数优化,-128~127的整数现在会直接从IntPool获取而不是新构造
...忘了
[Fix] 类构造 shorthand模式忘写了,现在补上了
[Feat][Impl] 类型声明现在接受一个表达式,原为Identifier。实现 var start: time.Time = time.now() 的效果
这是符合语法和语言特性的支持,类型为一等公民。类似Python的 <class 'type'>
[Impl] 修改了部分错误输出的细节
