:( cant wait for that to go away

Closing as this seems more trouble than it is worth. |

Obviously, it will be good to have something like this return in 0.5. |

Continuing the changes made in #10858 and #8432, this changes
for i = 1:length(a)tofor i in eachindex(a)throughout Base, and adds missingeachindexmethods forNumberandTupletypes (which are required for generic code).There should be no performance penalty to this, since in most cases
eachindex(a)inlines to1:length(a)anyway. But since usingeachindex(a)in loops is now the preferred style, it seemed best to do it consistently in Base, both to establish the habit and to catch any problems.
