[too] clever." The performance of the runtime matters, but its
robustness matters more.

Unmanaged memory
================

In general, the runtime tries to use regular heap allocation. However,
in some cases the runtime must allocate objects outside of the garbage
collected heap, in *unmanaged memory*. This is necessary if the
objects are part of the memory manager itself or if they must be

// A onePassProg is a compiled one-pass regular expression program.
// It is the same as syntax.Prog except for the use of onePassInst.
type onePassProg struct {
	Inst   []onePassInst
	Start  int // index of start instruction
	NumCap int // number of InstCapture insts in re
}

// A onePassInst is a single instruction in a one-pass regular expression program.
