We are phasing out coercions from strings to numbers. Removing them
from arithmetic operations would cause a lot of incompatibilities,
but we think (we may be wrong) that its need with bitwise operations
is much more rare. Coercion for bitwise operations is available
through the module 'bwcoercion.lua'.
