+vim.bindeval(str)					*python-bindeval*
+	Like |python-eval|, but
+	1. if expression evaluates to |List| or |Dictionary| it is returned as 
+	   vimlist or vimdictionary python type that are connected to original 
+	   list or dictionary. Thus modifications to these objects imply 
+	   modifications of the original.
+	2. if expression evaluates to a function reference, then it returns 
+	   callable vimfunction object. Use self keyword argument to assign 
+	   |self| object for dictionary functions.
+
+	Note: this function has the same behavior as |lua-eval| (except that 
+	      lua does not support running vim functions), |python-eval| is 
+	      kept for backwards compatibility in order not to make scripts 
+	      relying on outputs of vim.eval() being a copy of original or 
+	      vim.eval("1") returning a string.
