// export-test.slang
// A test to try out the basics of using libraries that can be linked (by downstream tools), via the HLSL `export` keyword.
// (This is in contrast to Slang modules and Slangs own linkage mechanisms)
// This didn't work for lib_6_2 when compiling via DXC (!). Even though it's stated elsewhere the feature is available from 6.1
