Expand description
PartitionHint demonstrates how to implement a custom enhancement:
positional enum arguments combined with an optional named integer argument.
§Text Format
Read[data => col:i64]
+ Enh:PartitionHint[&HASH, count=8]Each positional argument is a PartitionStrategy variant rendered with
the & enum prefix. The optional named argument count gives the target
number of partitions (0 / absent means “let the executor decide”).
