These checks would be omitted if the -noboundscheck compiler switch was provided.
This reminds me of Tony Hoare's lecture on null references being a "billion dollar mistake." He mentioned that he asked his Algol customers if they wanted the option to disable array bounds checking, and they all said no. I like this solution, and I will personally never ever turn that safety off.
Diggory asked this same question already. Does all of this also mean that a function with a ref parameter will automagically work with r-values? My one and only attempt at a Phobos pull request thus far will be mostly obsolete if this is the case. (Which is a good thing.)
