TypeScript Version: 2.4.1 / nightly (2.5.0-dev.20170629)

Code

import(`./${"module"}`)

Expected behavior:
Output of:

import("./" + "module");

Actual behavior:
Output of:

(import)("./" + "module");

Using "target": "es5" and "module": "esnext", TypeScript outputs invalid syntax for the dynamic import expression, wrapping it in parentheses.

Using a target of es2015 or higher, TypeScript outputs valid syntax with no parentheses.

This is only happens if import is given a template string.
