As mentioned in a /msg, I've seen some examples for XML::Parser that use it..You can find the link here... I think none of the examples for the current XML::Parser version use it though..
Perhaps out of context, and it may have changed later,
but this is a thread I found through Google on use English in Perl 6... Link to message archive is here..
I've wanted to use English in the stuff I write, but I have enough trouble remembering magic variables as it is... so, doesn't look like it's going to happen anytime soon.. :o)
