Read this original paper. Ignore the type theory part and look at the
examples. It makes a lot sense.

1. Implicit Parameter, Great, use it, and you like it, sometime it is even
necessary.
2. Implicit Conversion, BAD, use it can give you very good feel, but send
you into traps later. Very hard to read, debug and expand. (it is hard to
see the scope that you are in at certain point of code execution, and when
you expand it, you runinto 3, 4, even 5 way Implicit Conversions, too many
combination to maintain). |

发帖数: 1419 | 9 Second this. That being said, I find implicit parameters confusing when
interfering with event handlers. It could be confusing whether the event
handler callback is in the scope of the enclosing implicit parameter or not.
Implicit parameter is a great replacement for thread local variables. It
works well with continuation passing style.

List(1,2,3).toSet() ＝ (List(1,2,3).toSet).apply()
这返回false不是很正常吗？
