Module text

EXPLAIN ... AS TEXT support for LIR structures.

The format adheres to the following conventions:

1. In general, every line that starts with an uppercase character corresponds to a Plan variant.
2. Whenever the variant has an attached ~Plan, the printed name is $V::$P where $V identifies the variant and $P the plan.
3. The fields of a ~Plan struct attached to a Plan are rendered as if they were part of the variant themself.
4. Non-recursive parameters of each sub-plan are written as $key=$val pairs on the same line or as lowercase $key fields on indented lines.
5. A single non-recursive parameter can be written just as $val.
