Source Maps - language feature

Example from JavaScript, TypeScript:

{
 version: 3,
 file: 'min.js',
 names: ['bar', 'baz', 'n'],
 sources: ['one.js', 'two.js'],
 sourceRoot: 'http://example.com/www/js/',
 mappings: 'CAAC,IAAI,IAAM,SAAUA,GAClB,OAAOC,IAAID;CCDb,IAAI,IAAM,SAAUE,GAClB,OAAOA'
};

Example from Speedie:

linkage
 bannedclasses (file, process, shellstream, archive)
 // using these classes... even indirectly, will create an error
 // the error message will show the entire call-chain that reached these classes

Languages with Source Maps include JavaScript, TypeScript, Speedie

This question asks: Does the language support the generation of source maps?
