I’m just wondering if the julia compiler can treat a expression like x in (y,) the same as x == y, assuming that the right argument for in is always a 1-sized tuple. Moreover, what would be the performance difference between these two pieces of code? Edit: typo in the title

Sure looks like it! julia> @code_native debuginfo=:none 1 in (1,) pushq %rbp .cfi_def_cfa_offset 16 .cfi_offset %rbp, -16 movq %rsp, %rbp .cfi_def_cfa_register %rbp cmpq %rcx, (%rdx) sete %al popq %rbp retq juli…

Oh that’s cool! i guess there’s no performance difference then
