Feature #2709
Updated by nahi (Hiroshi Nakamura) almost 13 years ago
=begin Kernel#sprintf is very useful. I think the power lies within the ignorance of too many arguments. So one is free to decide which arguments he uses and which one he doesn't. This applies to a Ruby runtime where $VERBOSE and $DEBUG are false. Following the POLS (Principle of the least surprise), one would assume that changing the variables $VERBOSE and $DEBUG wouldn't change the behavior of Kernel#sprintf. But they do. $VERBOSE causes warnings when there are too many arguments. $DEBUG causes an ArgumentError when there are too many arguments. This isn't useful at all. I like the effect of $DEBUG according to threads, to raise uncaught exceptions from the thread. But in the case of Kernel#sprintf, it's just not useful. This behavior prohibits some power of Ruby. My suggestion: Remove the special behavior of $VERBOSE and $DEBUG in Kernel#sprintf. Thank you very much. =end
