I believe it would be interesting for mSL to add identifiers that perform binary operators left shift and right shift, since we already have $and, $not, $or and $xor.
I know it's easy to create them by aliases, however, as already said, it would be interesting for the language to have them.
$rshift(A,B)
$lshift(A,B)
A being a number and B the number of bits displaced.
Example of aliases that do this:
alias rshift return $calc($$1 // (2 ^ $$2))
alias lshift return $calc($$1 * (2 ^ $$2))
