know the location of every pointer to Go memory. Because of this,
there are restrictions on passing pointers between Go and C.

In this section the term Go pointer means a pointer to memory
allocated by Go (such as by using the & operator or calling the
predefined new function) and the term C pointer means a pointer to
memory allocated by C (such as by a call to C.malloc). Whether a
pointer is a Go pointer or a C pointer is a dynamic property

### Iterators

The new [`iter` package](/pkg/iter/) provides the basic definitions for

pkg unicode, var Hebrew *RangeTable
pkg unicode, var Hex_Digit *RangeTable
pkg unicode, var Hiragana *RangeTable
pkg unicode, var Hyphen *RangeTable
pkg unicode, var IDS_Binary_Operator *RangeTable
pkg unicode, var IDS_Trinary_Operator *RangeTable
pkg unicode, var Ideographic *RangeTable
pkg unicode, var Imperial_Aramaic *RangeTable
pkg unicode, var Inherited *RangeTable
pkg unicode, var Inscriptional_Pahlavi *RangeTable

<p>
Although the assembler takes its guidance from the Plan 9 assemblers,
it is a distinct program, so there are some differences.
One is in constant evaluation.
Constant expressions in the assembler are parsed using Go's operator
precedence, not the C-like precedence of the original.
Thus <code>3&amp;1&lt;&lt;2</code> is 4, not 0—it parses as <code>(3&amp;1)&lt;&lt;2</code>
not <code>3&amp;(1&lt;&lt;2)</code>.
