Yes, this pattern is very useful indeed, I also often use a similar
solution for generating code for string mixins on the fly. Do we already
have a name for it, by the way? I like to call it »IEDL for »Immediately
Executed/Evaluated Delegate Literal«, but that's probably just me.
No previously chosen name that I know of, but I like your name. Anyhow,
I'm impressed/pleasantly surprised. I didn't realize an IEDL could be
executed at compile time to produce a mixin string. If IEDLs are that
universally useful, then they definitely deserve some special case
performance optimizations, i.e. inlining and avoiding heap allocations.
Does anyone else have any interesting use cases for them?
I use them everywhere in the test suite. They behave a lot like comma
expressions (in that they allow you to put multiple expressions in a
place where you'd normally only be able to have one) but they allow
statements and declarations as well as expressions. This makes them
extremely useful in metaprogramming.
