It's a pity we cannot have non-ess users opinion here:)
>From the next version of ESS you will get smart SPC which will correct
whatever mess is before the cursor and also indent:
"foo_" into "foo <- "
"foo=" into "foo = "
"foo<-" into "foo <- "
and so on. Of course fully customized.
Originally I was thinking to implement a full set of smart operators,
but following Henning's suggestion it appeared to me that a very smart
SPACE should be pretty much enough for everything. It's also easier to
customize and considerably less intrusive.
