How does the quote go again, someone can learn Lisp in a week, except if they know C then it will take three weeks? I'm sure I've got the quote completely wrong (maybe it was about Forth?), but the essence is there: if you're learning a programming language it may take longer if you're already used to a programming language with different semantics compared to getting into it from scratch.

Also Raku is the most obvious language because it inherited the "it" variable ($_) from Perl, and "it" is unbeatable for writing obvious code (read a line, uppercase it, replace all numbers in it with dollar signs, and print it out again).
