This is a package for interfacing some inplace operations due to old julia code
module AltInplaceOperationInterface
add!(a::A, b::B) where {A,B} = error("add!(a::$A, b::$B) is not implemented")
minus!(a::A, b::B) where {A,B} = error("minus!(a::$A, b::$B) is not implemented")
pow!(a::A, b::B) where {A,B} = error("pow!(a::$A, b::$B) is not implemented")
max!(a::A, b::B) where {A,B} = error("max!(a::$A, b::$B) is not implemented")
min!(a::A, b::B) where {A,B} = error("min!(a::$A, b::$B) is not implemented")
export add!, minus!, pow!, max!, min!
