Dollar prefix in SASS variables not required

[JMitnik]

When compiling for example foo: bar;, the compiler is supposed to state something like "Invalid CSS after "foo: bar": expected "{", was "" ".

Instead, the compiler gives no error, and does not notice that there is a $dollar sign missing as a prefix for the variable. This should probably be fixed, unless I am missing something?

I'm not sure that it should state this? Without a dollar sign the expectation should surely be that it's a property and value? Just because you are using "foo" without the dollar sign and that would appear to not be a current valid CSS property, it doesn't mean that it couldn't be. SCSS is agnostic to possible CSS properties after all!

[JMitnik]

Right, but shouldn't the property: value only occur within the context of a code-block (such as within the context of a selector)? As it stands now, however, SCSS would check foo: bar; outside of any block, and would give an error as it expects a context. The only time in which foo:bar would occur outside of any context, is when you define SCSS variables (which are prefixed with the $). Yet, the fact that foo: bar is outside of any context, and has no prefix, should be identified as nor an error nor valid SCSS. Unless I miss anything?

Yes, in this case, the parser should check it's inside a block. That said, the focus has been on compiling valid scss...

I took a view at this and updated code as part of the pull request in #593
