On: Effective Go

[closeparen]

I make a sequence of calls during the service of a request. If any one of them fails I want to stop and return the error to the caller.

Having to check this in the particular case of every call at every later underlying every handler, does not make my software more reliable in than when it is simply guaranteed in general.

Explicit error handling can improve reliability in some circumstances, because it highlights corner cases which are easy to ignore otherwise.
