use FiniteField;
my $*modulus = 13;

say 10 + 5;  # 2
say 10 / 3;  # 12  (3*12 = 36 = 13*2 + 10)

Notes

• The dynamic variable $*modulus must be defined before calling any overloaded operator, otherwise the program will crash (no exception is handled so far).
• Modular division will not check for primality of modulus or any other requirements.
• Define a modulus for each lexical scopes you import the module in.
• Althouh the name of this repo is using a plural, the name of the module itself is singular, because you only use one finite field at a time.
• The main purpose of this module is to make writing cryptographic code easier.
