I'd say it's similar to currying, but not actual currying. 1) In this Smalltalk pattern, the extra default argument is fixed, provided at compile time; with currying, the extra argument is provided at runtime. 2) In Smalltalk, the result of any of the methods is the actual return value, whereas in currying it's a function until the last case. This is more like partial function application: http://en.wikipedia.org/wiki/Currying#Contrast_with_partial_function_applica... ion but that only solves 2), not 1). Blocks can go all the way. I'm not a functional programming expert, though! Steve Andres Valloud wrote April 2, 2015 11:38 AM:

It sure looks like an example of currying!

I agree with Andres about calling it a convenience method (and also not calling it a pattern), but is this not also an example of currying?

I would call that code an example of "convenience methods". In C, those things would likely be implemented in terms of "macros". The term "pattern" is overloaded, I wouldn't use it here.

Is there a name for the following pattern?
doSomething: arg1 ^ self doSomething: arg1 ifA: arg2Default
doSomething: arg1 ifA: arg2 ^ self doSomething: arg1 ifA: arg2 ifB: arg3Default
