The addition operator operators on scalars, not numeric values; you can pass it a string if you so desire. The operator must coerce the string into a number in order to do the addition.

From perlop:

Binary "+" returns the sum of two numbers.

The operator is monomorphic. Again, how is using the binary numeric addition operator not explicit about the intention to treat its operands in a numeric fashion?
