struct Transformer {
	env &types.Environment
mut:
	flag_enum_names map[string]bool
	// Track variable -> enum type mappings (inferred from assignments)
	var_enum_types map[string]string

Transformer performs AST-level transformations to simplify and normalize code before codegen. This avoids duplicating transformation logic across multiple backends (SSA, cleanc, etc.)

fn (mut t Transformer) transform_files(files []ast.File) []ast.File

transform_files transforms all files and returns transformed copies
