Release Notes
Added
- Scientific / exponential number literals. Floats can now be written as
<mantissa>e<exponent> — 6.022e23, 1.0e19, 1e-9, -2.5E6 (e/E, optional
exponent sign, bare-integer mantissa allowed). Out-of-range magnitudes follow
IEEE-754 (1e400 → inf). An e/E not followed by (an optional sign and) digits
is left untouched, so identifiers like e and exp are never mis-parsed.
Fixed
- Breakpoints fire inside async tasks — in both the native DAP (VS Code) and the
WASM playground debuggers. A breakpoint on a line that runs only inside an
async/async/spawn task (or via async/map/pool-map/async/all/channels) was
silently skipped because the scheduler ran every async task step in non-debug mode.
STOP + CONTINUE and step into/over/out now work at async breakpoints (verified e2e in
the playground). Known follow-ups: stepping across the scheduler into sibling tasks,
and variable-panel scoping to the paused task's frame at a cooperative stop.
- stdlib semantic-correctness sweep. A pass over divergence bugs across the standard
library: string/foldcase and string-ci=? now use full Unicode case folding
("Straße" folds to "strasse", so caseless comparison matches "STRASSE") — distinct
from string/lower; plus correctness fixes in equality (eq), shell, date/time,
typed arrays, and text helpers, with matching doc updates.
