+1 on the \-considered-harmful position.
If the desire is to save keystrokes, then we're optimizing for the wrong
To be sure, terseness is a desirable quality in code, but never at the
expense of clarity.
>From my position (C/C++/Java-ish background), the terseness is far
outweighed by the sheer "wtf?" factor; I look at the code and try to figure
out why ( is being escaped by \. The sorta-looks-like-a-lambda connection is
(IMHO) gonna be very tenuous to the typical JS programmer.
I find this construct to be extraordinarily hard to read, and it was legal,
would probably try to institute a coding convention on my projects that its
