STD.pm has since been updated to have the correct parsing -- the answer is that an integer literal never has a dot or 'e'. In r26812 I've just updated rakudo to match STD.pm, so this ticket can be closed. > This is part of the question of what distinguishes an integer from a > floating point number; it can't just be the presence of a decimal point > as the above examples show, but S02 isn't specific.

Just for completeness: .1 Not a legal number (leading digit required) 1e1 Float 1e-1 Float 10e-1 Float .1e1 Not a legal number (leading digit required) 1.e1 Not a legal number (digits required after dot) Closing ticket, thanks!
