Also, while 'raku' is the reading for 楽, which connotes easy, simple and other good things, it is also the reading for a bunch of other characters--namely, 落, which means or carries the connotation of falling, declining or otherwise missing the mark.

When I see the 'raku' transliteration in the context of Perl, I think of 落. Not sure if that says something about my subconscious perception of Perl or not, but I can't help but think 'Raku' is a bad choice for the name of a language mired in indecision and falling from public favor.

On another note, I find the inclination of tech projects towards poorly translated Japanese words amusing. It nicely compliments the phenomena you see in the use of random English words for the naming of Japanese cars, condo buildings, and other 'prestigious' products. So if you find that ridiculous, you should find these 'Japanese' technology names ridiculous as well.
