Question

Is it possible to send an anonymous message to an object? I want to compose three objects like this (think FP):

 " find inner product "
 reduce + (applyToAll * (transpose #(1 2 3) #(4 5 6)))

where reduce, applyToAll and transpose are objects and +, * and the two arrays are arguments passed to anonymous messages sent to those objects. Is it possible to achieve the same using blocks? (but no explicit usage of value:).

Answer 1

Perhaps what you really want to do is define a DSL inside Smalltalk?

With HELVETIA we explore a lightweight approach to embed new languages into the host language. The approach reuses the existing toolchain of editor, parser, compiler and debugger by leveraging the abstract syntax tree (AST) of the host environment. Different languages cleanly blend into each other and into existing code.
