From a conceptual standpoint, this sounds like the sort of thing
array languages like APL and J thrive on, so there's solid
precedent for the concept. I might suggest looking into
optimising compilers in that space for inspiration and such;
APEX, for example: http://www.snakeisland.com/apexup.htm
Of course, this comes with the caveat that this is (still!) some
relatively heavily-academic stuff. And I'm not sure to what
extent that can help mitigate the problem of relaxing type
requirements such that you can e.g. efficiently ,/⍉ your 4 2⍴"LR"
vector for SIMD on modern processors.
