Found this issue when trying to use less from the source. This works in dist because the class is compiled into a function.

### Example
let unreachableProxy = "http://127.0.0.1:8888"
try:
  let client = newHttpClient(proxy=newProxy(unreachableProxy), timeout=1)
  var res = client.getContent("https://github.com")
  echo res

Expected Output

Timed out a

Adding a plain text to the header of a compiled and optimized .js-file may be useful for multiple reasons:

• Adding metadata like version, compiler settings, date, ...
• Adding execution information, e.g. #!/usr/bin/env node

Should suppress --strict warnings.
