Should I use `Code.ensure_loaded?/1`?

[shahryarjb]

I have deleted all Code.ensure_loaded?/1 from runtime,

with Code.ensure_loaded?/1 my project took 67 millisecond after deleting it takes less than 300 microsecond. do not use this in runtime, especially when you have a loop

Very useful note.

Ensure_loaded is great if you can get away with doing it only once, like at code-gen time. ^.^

My work:

1. move some re-checks to compile time
2. change my structure
3. check some place with function_exported?
4. use try instead of. it is not recommended
