meteor/packages/dynamic-import

Remaining work:

• Future-proof findImportedModuleIdentifiers for real import(...)
• Source maps in development
• Debugger stops at reasonable points in dev tools
• Open another WebSocket? NO
• Make import(...) work on the server
• Modules are minified but not merged in production
  • Wrap modules with function to enable better minification
• Babel transform from import(...) to module.importAsync(...)
• Local module caching.
• Compact previous state representation
• Improve dependency resolution in packages/dynamic-import/server.js
• Report static import/syntax/etc. errors for async files
• What about old/new versions of code?
• What about package pseudo-globals (imports)?
• What about dynamic stubs?
• Avoid creating dynamic files on the server.
• Mp.dynamicImport could be implemented without the fallback on the server if we were sure the server had no dynamic files.
• Batch multiple __dynamicImport method calls.
• Make sure client-only reloads work (revisit _read caching).
• Make sure path manipulation is Windows-safe.
• Install dynamic modules with correct meteorInstall options.
• Tests!
