The purpose is to make programs safer, rather than provide any hints
for optimisation. The current system is type-safe and gives a
"discarding const" compiler warning if people try to pass const
objects to functions as non-const arguments - these seem like useful
features. It's not clear to me what the actual benefit would be if we
only had non-const vectors and matrices.
