Compilation error in template when accessing the fields of a tuple constant

[lscrd]

Description

The following program doesn't compile:

type Point = tuple[x, y: int]

const Origin: Point = (0, 0)

template next(point: Point): Point =
  (point.x + 1, point.y + 1)

echo Origin.x      # OK: the field is visible.
echo next(Origin)  # Compilation error: the field is not visible.

Known Workarounds

If the value is provided with explicit field names, the compilation is successful.

Additional Information

The problem occurs only for constant tuples with explicit field names initialized with a tuple without explicit field names.
