Well to me it seems that `:` is no more special here than other listed
tokens (probably except `}`). E.g.:
- After `)`: ((Foo)yield).bar();
- After `{`: Object[] arr = {yield};
- After `;`: for(int i=0; i<10; yield(i++)) {}
`yield` keyword is always preceded by one of X, Y, Z tokens doesn't
mean that any `yield` character sequence which follows X, Y or Z
tokens is necessarily a keyword. Only where YieldStatement production
is expected we treat it as a keyword.
Btw `yield` keyword can also appear after `else` token: if(foo) yield
bar; else yield baz;
With best regards,
