In general, when writing code programmers spend much more time with code which is either compile-time, or run-time, incorrect. If I wrote perfect code first time, then my job would be much, much easier! It is the compiler's fault, but in practice, it makes the library very, very hard to use.

Speaking from experience, 10 minutes is too much. I've used Phoenix v2
extensively and I've found that after reading the docs first before
trying to do anything with it that I got it easier that way. That said
I haven't tried Phoenix v3 though I've been debugging Spirit code
since the 2.x days -- again reading the docs, keeping them handy, and
not getting scared with compiler barfage.

I'm not saying there's no learning curve -- it involves reading the
documentation, trying things out, and getting the "spirit" of the
library and the semantics of usage.

But that's just me though and I recognize that others might not have
it as good as I did when I was learning both Spirit and Phoenix.

Exactly my point of contention too.
