import source
The import source statement behaves like regular import statements, but it can only import a module using the default import syntax, and results in an object representing the module's unevaluated source code. The module can be imperatively evaluated later using a method provided by the source code object.
To use import source, the target module has to support source phase imports. Currently, only WebAssembly modules support source phase imports, which result in WebAssembly.Module objects. JavaScript module source objects will be added by the ECMAScript Module Phase Imports proposal.
Syntax

module-name-

Import attributes are also supported in import source statements, and are handled the same way as in regular import statements.
