There is an effect where some things work well on some languages, but fail completely when translated to others because of superficially unrelated features.

Compile and run time code generation seem to be one of those things. Having a mostly pure language (even when there aren't guarantees) makes them much saner.

1 - Pre-compile time generation, by its turn seems to never work very well. And if there is developer interaction between the code generation and compiling, than it's always a disaster.
