String import an entire directory

[Neia Neutuladh]

At my job, I put together a database migration tool for our 
services. It scans for resources in your JAR file with an 
appropriate path, interprets them as SQL scripts, and applies 
them to the database if it hasn't been done yet.

I want to implement this in D. However, while D allows you to 
import individual files, it doesn't let you import an entire 
directory.

I can make a prebuild script to generate code for this, but I'm 
wondering: do other people find themselves needing this 
periodically? If so, I can write a DIP for it, or at least 
publish a codegen tool that other people can use.
