For information, searching in info (with / or s or Ctrl+S) these
days uses extended regexps. So, to search for =(, you need to
search for =\( or toggle regexp matching off first with R. See
info info / for details.

Already in ksh86. In ksh86 you could actually also use A (B) in
place of A <(B) though it looks like it was removed in later
versions. rc also had process substitution with a different
syntax IIRC.
