dynamically, these has() calls will try to load them.  If only one can be
loaded at a time, just checking if Python 2 or 3 are available will prevent
the other one from being available.

To avoid loading the dynamic library, only check if Vim was compiled with
python support: >
	if has('python_compiled')
	  echo 'compiled with Python 2.x support'
	  if has('python_dynamic')
	    echo 'Python 2.x dynamically loaded'

8. MzScheme setup				    *mzscheme-setup* *E895*

Vim requires "racket/base" module for if_mzsch core (fallback to "scheme/base"
if it doesn't exist), "r5rs" module for test and "raco ctool" command for
building Vim.  If MzScheme did not have them, you can install them with
MzScheme's raco command:
>
  raco pkg install scheme-lib       # scheme/base module

The SNiFF+ support was removed at patch 7.4.1433.  If you want to check it out
sync to before that.

	|expression|).  Returns the expression result as:
	- a Integer if the Vim expression evaluates to a number
	- a Float if the Vim expression evaluates to a float
	- a String if the Vim expression evaluates to a string
	- a Array if the Vim expression evaluates to a Vim list
	- a Hash if the Vim expression evaluates to a Vim dictionary
	Dictionaries and lists are recursively expanded.

				|Funcref|). It is equivalent to Vim's
				function().

	vim.buffer([arg])	If "arg" is a number, returns buffer with
				number "arg" in the buffer list or, if "arg"
				is a string, returns buffer whose full or short
				name is "arg". In both cases, returns 'nil'
				(nil value, not string) if the buffer is not
				found. Otherwise, if "toboolean(arg)" is
				'true' returns the first buffer in the buffer

vim.eval(str)						*python-eval*
	Evaluates the expression str using the vim internal expression
	evaluator (see |expression|).  Returns the expression result as:
	- a string if the Vim expression evaluates to a string or number
	- a list if the Vim expression evaluates to a Vim list
	- a dictionary if the Vim expression evaluates to a Vim dictionary
	Dictionaries and lists are recursively expanded.
	Examples: >vim
	    :py text_width = vim.eval("&tw")

append({n}, {str})
		Appends a line after the line {n}.
line		Returns the current line of the buffer if the buffer is
		active.
line = {str}    Sets the current line of the buffer if the buffer is active.
line_number     Returns the number of the current line if the buffer is
		active.

	::vim::lbase					*tcl-var-lbase*
	This variable controls how Tcl treats line numbers.  If it is set to
	'1', then lines and columns start at 1.  This way, line numbers from
	Tcl commands and vim expressions are compatible.  If this variable is
	set to '0', then line numbers and columns start at 0 in Tcl.  This is
	useful if you want to treat a buffer as a Tcl list or a line as a Tcl
