There are two kinds of language constructs that uses the "import" 
keyword. One is the "Import Declaration" [1] which is the most common 
one and is used to import other symbols. The other language construct is 
the "Import Expression" [2], which is used to read a file at compile 
time and put its content into a string literal in your source code.

Anything specified to the "stringImportPaths" build setting will be sent 
to the compiler with the -J flag.
