def IsMulCommutative.instCommMagma {M : Type u_2} [Mul M] [IsMulCommutative M] : CommMagma M

A magma which IsMulCommutative is a CommMagma.

This is primarily used to deduce the bundled version from the unbundled one for commutative subobjects in a noncommutative ambient type. As such this is only available inside the IsMulCommutative scope so as to avoid deleterious effects to type class synthesis for bundled commutativity.

See note [commutative subobjects].

def IsAddCommutative.instAddCommMagma {M : Type u_2} [Add M] [IsAddCommutative M] : AddCommMagma M

An additive magma which IsMulCommutative is a AddCommMagma.

This is primarily used to deduce the bundled version from the unbundled one for commutative subobjects in a noncommutative ambient type. As such this is only available inside the IsMulCommutative scope so as to avoid deleterious effects to type class synthesis for bundled commutativity.

See note [commutative subobjects].
