I believe that most tuple functions when inlined should occuppy almost the same as a function call, so I dont belive your estimative would be correct. With register allocation playing right, there would be less, or none, need to save registers and the results being used directly too, the whole using function could be even smaller when using the inlined one.
It's possible. Still there code size will be significantly bigger in comparison with offline implementation, right?
Probably the other way around. The compiler would have to emit code to make the function call (pass arguments, make the call machine code, reallocate the return value in another register). And *that* code would be bigger than using the inlined version of tuples, which wouldnt need to call anything, just access the value directly. And if possibilities to optimize away other instructions through the possible optimizations that inlining offers.
