Why the paths in Phoenix require an atom instead of a function?

[peerreynders]

Runtime dynamic binding:

iex(4)> arg = "Hello"
"Hello"
iex(5)> IO.puts(arg)
Hello
:ok
iex(6)> Kernel.apply(IO, :puts, [arg])
Hello
:ok
iex(7)> 

Kernel.apply/3

I want compile errors from router.ex, but everything compiles fine. (?)

The problem with this syntax is that it would introduce a compile-time dependency on the HelloController module. You don’t want all of your controllers recompiled when you change the router.
