Conversation
Introduce `*` as an infix data-expression operator that binds tighter than `+`/`-` and looser than prefix `!`, left-associative. - Grammar: `data_mul` token in `data_infix` - AST: `MulOp` node + `DataExpr::MulOp` - Parsing: `mul_op_parse` and a dedicated Pratt precedence level - Analysis and lowering to `tx3-tir`'s `BuiltInOp::Mul` - Spec (v1beta0): lexical, grammar, and type-system updates Semantics: `Int * Int`, plus `AnyAsset * Int` / `Int * AnyAsset` asset-quantity scaling.

Summary
Adds the multiply (
*) operator to the Tx3 data-expression language.tx3.pest):data_multoken added todata_infix. Disambiguated from theinput*block flag by grammatical context.MulOpnode andDataExpr::MulOpvariant.mul_op_parseplus a dedicated Pratt precedence level —*binds tighter than+/-, looser than prefix!, left-associative.tx3-tir'sBuiltInOp::Mul.Semantics:
Int * Int(product),AnyAsset * IntandInt * AnyAsset(scale asset quantities).AnyAsset * AnyAssetis undefined.Tests
Parser tests for the basic form and precedence (
2 + 3 * 4→2 + (3*4);3 * 4 + 2→(3*4) + 2). Full suite green (171 + 4 doc-tests). Verified end-to-end throughtx3c build --emit tir-json:quantity * 2 + 445lowers toAdd[Mul[quantity, 2], 445].Depends on
tx3-lang/tir#1 (
BuiltInOp::Mul). Bump thetx3-tirdependency to the release that includes it before merging.🤖 Generated with Claude Code
