Environment details

• Programming language: TS
• OS: Linux
• Language runtime version: v18.12.0
• Package version: main branch

Steps to reproduce

1. Run generator
2. See badness in output

 * Equivalent to `method.name.toCamelCase()`, but returns a NodeJS Stream object.

This is already visible in the wild (e.g.), and it's basically a missing set of curly brackets in _util.njk. I'll put in a fix for it as part of some work I'm already doing in the generator. (Just bookkeeping here.)
