My pynto https://github.com/punkbrwstr/pynto https://github.com/punkbrwstr/pynto is a similar framework for creating dataframes, but using a concatenative paradigm that treats the frame as a stack of columns. Functions ("words") operate on the stack to set up the graph for each column, and execution happens afterwards in parallel. Instead of function modifiers like @does it uses combinators to apply quoted operations to multiple columns. The postfix syntax (think postscript or factor) is unambiguous, if a bit old-school.
