There is another issue with passing functions. 
Suppose, the following code

	function me1(string scalar he)
	{
      	...
		if (he=="he1") y = me2(x, &he1())
		else if (he=="he2") y = me2(x, &he2())
		else if (he=="he3") y = me2(x, &he3())
		...
		return(...)	
	}

where 

	function me2(x, he)
	{
	      ...
		y = (*he)(x)
		...
		return(...)	
	}

Is it possible to change -me1()- such that 
the different -he-'s do not have to be typed out
explicitly?

If Mata had macro expansion, I would type

	function me1(string scalar he)
	{
      	...
		y = me2(x, &`he'())
		...
		return(...)	
	}

However, such things don't work in Mata. Does anyone
know a solution to this problem?
