// Avoid dart2js optimizations that alter the JavaScript stack trace. (1)
// dart2js inlines methods in the generated JavaScript which leads to missing
// frames in the stack trace. (2) Minification obfucsates names. Both issues can
// be addressed offline by post-processing the stack trace using the source map
// file.
