You should try one of the many fishes where bones aren't an issue
then. Salmons have strong and thick bones that are easily removed with
a special plier before preparing the fish. Salmon is delicious when
served raw as sushi or with a mustard sauce and potatoes, or it can be
served cooked, fried or barbequed with a variety of sauces.
Another alternative you could consider is herring. Small herrings have
very soft bones, you barely notice them while eating them. They tast
wonderful when served with lingonberries.
Also, the commandline shell named fish contains no bones.

Ruby fails on minimalism. There are other factors to take in, though.
Very few people spend many hours per week writing shellscripts,
therefore, a shellscript language should be very simple and
consistent, otherwise you keep forgetting little details all the time.
If you use a language for many hours every day, the learning curve is
less important than brevity and readability.
I actually have relatively little experience with Ruby, but what
little I have tells me that while Ruby is a somewhat complex language,
it is readable, consistent and well designed for the most part. Perl,
on the other hand, is not. So I would argue that Ruby might be a very
well designed language for people who intend to use it a lot. But then
maybe I simply haven't seen enough of Ruby.

Haven't used Pike, though I am under the impression that it's mostly
PHP without the train wreck.

I don't know about innovative. From the 'C infrequently asked questions':
18.6: How can a process change an environment variable in its caller?
Only by force. Example code for Unix:
memmove(getppid() + getenv(NULL), getpid() + getenv(NULL),
sizeof(environ));
Though I must say I like the fish solution better. ;-)
