// Type inference makes the <T> argument to When optional when the parameters are the same type

This is pretty flaky mind you. Sometimes type inference works, sometimes it doesn't and you have to be explicit. It is something that may have improved in more recent releases, but IIRC some issues remain.

The Byte example shows that flakiness, but it does seem to work well in 10.4.1 - also with regards to Error Insight.

How I wish we could have generic functions outside of classes or records.

That or something like this.

In the exactly same situation (using extra unit for just one 3-lined function annoys me like hell) I ended up with most trivial solution - I named my functions `IfTh`.

Mine - in use for the last 20 years - is named iif. Yes, I was a FoxPro user in the 1990s! I was looking at something in one of my programs a few weeks back and realised it was there to save space when saving to floppy disk. If there's such a thing as a code archaeologist they could have a great time with my codebase.

This one is nice as well, SQL-style
