The lambda printer fell back to a graph dump for +inf, -inf and NaN. Spell infinities as overflowing literals (1e999, -1e999) and the canonical NaN as (0.0, 0.0) div. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Alternatively, we add proper keywords to Corgi. I can do it if we go this route. |

The lambda printer falls back to a graph dump for +inf, -inf and NaN. This removes the fallback seen in
tour.ddpandf64_math.ddp, both of which now reportfallback=0under--check-lambdas. A related lint is in #1079.The lexer lives in corgi and has no
inf/nanwords, so the spelling uses what it already accepts. A literal that overflowsf64parses as an infinity (1e999,-1e999), which cannot shadow a binding. NaN is(0.0, 0.0) div, the canonical quiet NaN0x7ff8000000000000that corgi gives every computed NaN. Floats compare by total order, so NaNs with other bits are distinct values that only data can carry, and the printer still falls back for those.Posted by Claude Code.
