How to specify a function call instead of field reference in a partial?

@moorereason This issue is related to How to convert a string to a "symbol" or vice-versa.

call expects a function identifier, not a string containing that…

call
	Returns the result of calling the first argument, which
	must be a function, with the remaining arguments as parameters.
	Thus "call .X.Y 1 2" is, in Go notation, dot.X.Y(1, 2) where
	Y is a func-valued field, map entry, or the like.
	The first argument must be the result of an evaluation
	that yields a value of function type (as distinct from
	a predefined function such as print). The function must
	return either one or two result values, the second of which
	is of type error. If the arguments don't match the function
	or the returned error value is non-nil, execution stops.

So need to figure of if converting a string to an identifier is possible.
