Research direction

Inspect the Go parser's source code in src/cmd/compile/internal/syntax/ to understand how []byte literals are currently parsed and represented. Identify where the large node trees are created and consider alternative representations, such as storing the literal's bytes directly as a string of byte values or using a constant array approach.
