I have no idea. It doesn't look right.
Sometimes it has the same pattern for different macros, so there is a valid
reason to do so, but in general it is almost always blindly calling compile
before any evaluation.
There is something else I have noticed.
cpython always compiles. Ironpython compiles only if compile is called.
The patch I have submitted (https://github.com/IronLanguages/main/pull/191)
is trying to be clever about it.
Any direct method does cache, but it does not compile (compile is
expensive, I learned it hard way :-)
Compile does cache, but if the cached version is not compiled, it gets
replaced with compiled one.
asciidoc running with patched version of ironpython performs reasonably.
