...39;s an assignment. On
the other hand, both "<" and "-" have multiple other uses. This leads
to lots of possibilities for confusion:
x <--5
x < -5
x <- 5
are easily confused, whereas
x _-5
x < -5
x _ 5
are not.
(Of course, I actually prefer the Pascalian :=, but I realize that
puts me in a double minority :-).

No problems if your space key is actually working and you know
how to use it and (I suppose) care about communicating to your audience.

My main objection is to the use of _ without spaces. Every week or
so I misread a post on R-help or S-news because the code is lacking
spaces and I parse it wrongly, and I know I am not alone from the
frequent remarks from other reade...
