If Wx isn't that large, I might take a stab at porting it... who knows. :)

You will have to tell me how:

^10000.grep( *.is-prime).say; # Retrieve prime numbers from 0-10,000

Is incomprehsible bullshit and:

given $value {
    when Str { ... Do string handling ... }
    when Int { ... Do integer handling ... }
    when Bool { ...Do boolean handing ... }
    default { ... Fallback handling... }
}

Is mind wanking....

If you've really tried the language, why not give it a comprehensive review?
