Isn't it more about what the typical program looks like? The generic languages like Rust and C++ generate a ton of functions, wrapper types, and indirections that need to be seen through and mostly removed by the compiler.

In C++, when compiling:

   for (; *it; ++it) { }

it may look simple but deref is a function you insert (deref operator), `++it` is a function and so it continues on, with new function to generate each time it's a different iterator or even the same iterator with different template parameters.
