You wrote "In general reversed/converse has no meaning for block." That's entirely an artefact of representing blocks of different arities by the same class. In my own Smalltalk, NiladicBlock, MonadicBlock, DyadicBlock, ... are different classes. To put it another way, your statement has exactly

Not really. You can use ClassVariables though. Here's an example for Sets: Object subclass: #MyClass instanceVariableNames: '' classVariableNames: 'MyClassVar' package: 'MyPackage' MyClass class>>initialize super initialize. MyClassVar := Set new. MyClass>>foo self bar: MyClassVar

[Pharo-users] Literals

You know, literals are quite useful in case when you want to shorten some object initialization. For example #() and {} for arrays and $[]for byte arrays. However, if there is a way to add custom literals, for example for sets (something like #{} I guess)? how to do it? and can some special kind of

Re: [Pharo-users] UFFI - Could not coerce arguments

hi, it all depends on how you are declaring your types. here, for example you are passing aTF_OutputArray getHandle that’s a “void*” value (an ExternalAddress or ExternalData object), and in declaration you have (if I read correctly): TF_Output * so, first question is: if TF_Output != void
