Description

By allowing multiple targets, transpilation speeds would be vastly improved for any project doing this already, as the AST only needs to be generated once.

Research direction

The issue proposes transpiling to multiple targets while generating the AST once, but it names no files, tests, entry points, or acceptance criteria. Start by locating the compiler’s target-selection and AST-generation paths, then identify existing tests for single-target transpilation. Done should include defined multi-target behavior and coverage showing the AST is reused.
