Hello,
I'm currently working on an embedding of the miniKanren logic programming language in Pharo (http://minikanren.org/ <http://minikanren.org/>) and I have run into an issue with the method compilation internals I was hoping someone could shed some light on:
miniKanren has an operator, fresh, that basically evaluates a block and returns a logic variable. My current syntax for a conjunction of logic variables is:
var1 and: var2
When I try to use the same syntax for fresh:
var1 and: [ :var2 | var2 ]
Compilation fails with "Warning: and: (or:) takes zero-arg block" which seems on first glance to come from the compiler attempting to inline my and: call.
Another thing we can do⦠we could remove the warning in the method #isInlineAndOr. Then the and: would be compiled as a message as in the non-block example. Marcus
