      The new <a href="/pkg/io#SectionReader.Outer"><code>SectionReader.Outer</code></a> method returns the <a href="/pkg/io#ReaderAt"><code>ReaderAt</code></a>, offset, and size passed to <a href="/pkg/io#NewSectionReader"><code>NewSectionReader</code></a>.

Redeclaration does not introduce a new variable; it just assigns a new value to the original.
</p>

<pre>
field1, offset := nextField(str, 0)
field2, offset := nextField(str, offset)  // redeclares offset
a, a := 1, 2                              // illegal: double declaration of a or no new variable if a was declared elsewhere
</pre>

<p>

The non-blank variable names on the left side of <code>:=</code>
must be <a href="#Uniqueness_of_identifiers">unique</a>.
</p>

<pre>
field1, offset := nextField(str, 0)
field2, offset := nextField(str, offset)  // redeclares offset
x, y, x := 1, 2, 3                        // illegal: x repeated on left side of :=
</pre>

<p>
Short variable declarations may appear only inside functions.

at the beginning, as in <code>first_arg+0(FP)</code> and <code>second_arg+8(FP)</code>.
(The meaning of the offset—offset from the frame pointer—distinct
from its use with <code>SB</code>, where it is an offset from the symbol.)
The assembler enforces this convention, rejecting plain <code>0(FP)</code> and <code>8(FP)</code>.
