Thanks to @lexidor and @aloiret for these changes:

• negative integer strings (e.g. "-123") are now supported; any string can now be converted to an int if - ignoring leading zeroes - the int converts back to the same string.
• the disallow_ambiguous_lambda typechecker option no longer raises errors in type-assert
• the disable_lval_as_an_expression typechecker option no longer raises errors in type-assert
