Remarkable how easy it is to inspect different levels of #codegen in #JuliaLang - from intermediate representations, through #LLVM IR, to native, e.g.:
```
julia> @code_llvm 1+2
; Function Signature: +(Int64, Int64)
; @ int.jl:87 within `+`
define i64 @"julia_+_735"(i64 signext %"x::Int64", i64 signext %"y::Int64") #0 {
top:
%0 = add i64 %"y::Int64", %"x::Int64"
ret i64 %0
}
```
But there is no `@code_source` macro (should return, e.g., `1 + 2`) 😊
