I think it is high time to reconsider the messaging concerning the benefits of programming in Julia. Instead of focusing on claims of raw speed (which are easily cast in doubt), we should focus on productivity and the benefits of extensibility (Generating finite-difference stencils - #7 by PetrKryslUCSD) and such.
This is not to detract from the point of the OP which I believe is sincerely conceived, even though I must say all my experiences on this forum have been positive (with very few exceptions): it is a welcoming and receptive community. I have been helped courteously and promptly by countless masters of the language, no matter how trivial or self-evident some of the solutions may have seemed to them.
