"__v" warnings

[henrik]

Warnings when booting Phoenix:

web/views/layout_view.ex:2: warning: the underscored variable "__v" is used after being set. A leading underscore indicates that the value of the variable should be ignored. If this is intended please rename the variable to remove the underscore

This looks a likely culprit: https://github.com/doomspork/slim_fast/blob/c1b581fc0e222d54eeef98761f72c3fa874b28dd/lib/slim_fast/compiler.ex#L18

You're on top of it @henrik, thanks! Would you like to take a stab at fixing this one? I haven't reproduced it myself but it suspect it will be straightforward.

[henrik]

Sure, I'll give it a shot!

I'm on Elixir 1.1.1 – maybe the warning is a new thing.

Edit: Nevermind. I'll check out 1.1.1.

These all work as expected but none raise a warning:

# Controller
def false_attribute_value, do: false
def string_attribute_value, do: "test"

/! Slim
.container role="main" test=false_attribute_value
.container role="main" test=string_attribute_value

<!-- HTML -->
<div class="container" role="main">
<div class="container" role="main" test="test">

Definitely a 1.1.1 warning, just confirmed. Have a go at it @henrik 👍

How about this: #42

[doomspork]

Closed via #42, thanks again @henrik 👍
