```# specification of operators for HighIR version of the IR.  Each line (other than comments)
# specifies an operator using five fields, which are separated by ":".  The fields are
#       name
#       argument type           (optional)
#       result arity
#       arity
#       comment                 (optional)

# Operations with effects are denoted by a "!" as the first character of the line.
