For example, the the library '(mpl algebraic-expand)' exports\nthe single procedure 'algebraic-expand'. When designing R6RS libraries\nwhich make use of MPL libraries, many users will choose to import\nindividual MPL libraries a la carte. However, when you're\nexperimenting at a REPL, it can get tedious to import the libraries\nindividually. Thus the '(mpl all)' library is provided so that you can\nget the common parts of MPL in one import.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdharmatech%2Fmpl","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdharmatech%2Fmpl","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdharmatech%2Fmpl/lists"}
