ahoy, it seems like str-replace is not working. given the following input ``` $find: 'hello'; $replace: 'ahoy'; $input: 'hello Toolkit!'; @debug str-replace($find, $replace, $input); ``` the output is `DEBUG: hello`. basically, it seems to return the `$find` string no matter what. my current Bundler versions are: ``` Using sass (3.2.12) Using compass (0.12.2) Using toolkit (1.3.8) Using bundler (1.3.5) ``` thanks
