Sometimes you just make the stupid mistakes

I guess because the variable name doesn't hint the type. A variable like isAvailable is most likely a boolean. This is a value from a dictionary which could be any type and automatic type conversion could save your ass at runtime.

Which language? For some languages this would avoid casting to bool implicitly and fail for "truthy" values like ['an array', 'with', 'content'].

Edit: I would accept the diff above for any language where it can make a difference and you are expecting a boolean. Explicit is better than implicit.

@zvyn i understand that. It's ruby btw. However, i still feel it was unnecessary. The reviewer was right.
