translator enhancement needed

[Mark S. Miller <mark>]

I need the following translator enhancement:

When I write in Smalltalk:

	[ statement1. statement2 ] mutex: aSema4.

It needs to translate into the C++:

	{
	    MUTEX_BEGIN(aSema4);
	    statement1;
	    statement2;
	}

Until I hear otherwise, I'll go ahead programming in Smalltalk
assuming this enhancement will happen.  Reasonable?
