simpLib.++ : simpset * ssdata -> simpset

SYNOPSIS
Augments simpsets with ssdata values.

LIBRARY
simpLib

DESCRIBE
The ++ function combines its two arguments and creates a new simpset. This is a way of creating simpsets that are tailored to the particular simplification task at hand.

FAILURE
Never fails.

EXAMPLE
Here we add the UNWIND_ss ssdata value to the pure_ss simpset to exploit the former's point-wise elimination conversions.
   - SIMP_CONV (pure_ss ++ boolSimps.UNWIND_ss) []
               (Term`!x. x ==> (?y. P(x,y) /\ (y = 5))`);
   > val it = |- (!x. x ==> (?y. P (x,y) /\ (y = 5))) = P (T,5) : thm

COMMENTS
The ++ identifier is not an infix by default, and so needs to be declared as such at the ML top-level loop, e.g.:
   - infix ++;
   > infix 0 ++
