Then you definitely did not grok it. What I gather from https://en.wikipedia.org/wiki/Icon_(programming_language)#Goal-directed_execution https://en.wikipedia.org/wiki/Icon_(programming_language)#Go... is that Icon's goal directed execution is more like `react whenever` in Raku (https://docs.raku.org/language/concurrency#whenever https://docs.raku.org/language/concurrency#whenever) Junctions autothread. What does that mean? Using a Junction as an ordinary value, will cause execution for each of the eigenstates, and result in another Junction with the result of each of the executions. An example: # a simple sub showing its arg, returning twice the value sub foo($bar) { say $bar; 2 * $bar } # a simple "or" junction my $a = 1 | 2 | 3; say foo($a); # executes for each of eigenstates # 1 # 2 # 3 # any(2, 4, 6) Documentation: https://docs.raku.org/type/Junction https://docs.raku.org/type/Junction
