The way Sass currently handles plain-CSS
@imports is different than the way it handles other plain-CSS at-rules, in a few ways. Once we get rid of dynamic Sass@imports (#3513), we'll want to start treating plain-CSS@imports the same as any at-rule, which means removing these custom behaviors.The specific behaviors at issue are:
@import, as in@import "foo.css", "bar.css".@import url("#{'"'}")currently produces@import url('"')and@import url("#{'\a'}")currently produces@import url("\a"). For other at-rules these produce@foo url(""")and@foo url(" "), respectively. Note that this specifically only occurs for aurl()(the only context in which interpolation is allowed in a static import) that contains a quoted string.The first difference can be detected at parse-time. We don't want to emit deprecations for every interpolation in a static import, so for the second we'll have to detect interpolations that specifically contain characters that have semantically different handling for string-style interpolation, which are quotes, backslashes, carriage returns, line feeds, and null characters. Fortunately, these are generally unlikely to be present in actually-imported URLs, so this shouldn't cause too much user pain.
