Hi guys I realized that value: valueWithPossibleArguments: cull: and others supernice messages do not have the method comments they deserved. cull: anArg ^numArgs = 0 ifTrue: [self value] ifFalse: [self value: anArg] => I started https://pharo.fogbugz.com/f/cases/19689/Add-method-comments-to-cool-block-me... cull: anArg "Execute the receiver with one or zero arguments depending on the receiver number of required arguments." "([ 12 ] cull: 13) >>> 12 " "([:x | x + 12] cull: 3) >>> 15 " ^numArgs = 0 ifTrue: [self value] ifFalse: [self value: anArg] Any takers? because it would be really nice to say to newcomers that our core libraries are super cool.
