pub fn parse_nl_text(txt: &str) -> Result<NlProblem, String>Expand description
Parse .nl text content. Public so tests can use string literals.
Degree-2 bodies are recognized as the token stream is read, so their
Expr trees are never built (gh #588, Q5); POUNCE_DBG_NO_QUAD=1
turns that off and restores the pre-Q5 parse exactly, which is what the
A/B reference and gh #540’s guard test need. See
parse_nl_text_with_quadratic for the same switch as a parameter.
