Improve TQL parsing for pipeline arguments and assignments
This release improves TQL parsing for multi-pipeline operators and assignments in expression and package contexts. It eliminates recovery nodes for several valid constructs, improving syntax-tree accuracy and highlighting.
🚀 Features
Multiple pipeline arguments
Operators can now take multiple pipeline arguments separated by commas, as required by operators such as fork_merge:
fork_merge {
head 1
}, {
tail 1
}
Previously, only a single { … } pipeline argument parsed correctly, and pipelines using more than one produced a syntax error.

🐞 Bug fixes
Assignment expressions in syntax trees
Assignments now parse in expression contexts such as conditions:
if ($x = 42) {
}
This keeps syntax trees aligned with the TQL engine instead of producing recovery nodes for valid assignment expressions.
Package dollar variable parsing
Package operator bodies now parse dollar-prefixed assignment targets, package constants, and trailing function-call commas without recovery errors:
$into = $log.parse_ssv(
header=amazon::$header,
)
Syntax highlighters can now color $into as one variable when it appears on the left-hand side of an assignment.
