Logger / Helper

[unvoodoo]

Just couple thoughts about logger/helper. Want to hear your thoughts.

Logger extension
Logger interface could have WithCallerSkipCount method to return a new Logger (similar to Fields method). This way we could rebuild logger in NewHandler constructor with +1 skip.

DefaultLogger extension
It looks like common pattern of micro logger's usage is to call logger.Info / logger.Error, etc. So maybe interface type of DefaultLogger should also respect that and have Info/Error methods? I mean Helper-like interface. Or it can be of type Helper?

Helper + Logger
Do we need Helper apart from Logger actually? Wouldn't it be clearer to add methods from Helper to interface and implementations?

• Eliminates Logger/Helper confusion.
• Easier to add methods like WithCallerSkipCount (that return new Logger) to codebase - now you have to add it in Helper (to return new Helper) and in Logger (to return new Logger).
