There is quite possibly something too that, and as I imagine
with more functional experience it will come easier to me.

However, I still think imperative code is generally easier to
reason about because (usually) each line of code is performing
a single task, whereas with functional coding the goal seems
to be to cram as many operations as possible into a single line
(I know that isn't the real reason, it just seems that way at
times).  Trying to 'unroll' everything in your head can be a
challenge.  Throw in a lambda function or two with
the mess of braces/symbols and then you have a real puzzler.
