Weird behavior between ruby versions with ->{ } proc syntax. Any explanation?

jacegu / roman_numerals.erl
Created April 15, 2013 14:39
Roman numeral kata in erlang. Wondering if there is a better/more idiomatic way to approach the problem.
-module(kata).
-include_lib("eunit/include/eunit.hrl").
to_roman(Arabic) when Arabic >= 50 -> string:concat("L", to_roman(Arabic - 50));
to_roman(Arabic) when Arabic >= 10 -> string:concat("X", to_roman(Arabic - 10));
to_roman(Arabic) when Arabic >= 5 -> string:concat("V", to_roman(Arabic - 5));
to_roman(Arabic) when Arabic =:= 4 -> string:concat("IV", to_roman(Arabic - 4));
to_roman(Arabic) when Arabic >= 1 -> string:concat("I", to_roman(Arabic - 1));
to_roman(_) -> "".
