<a name="l112"></a>* Goto labels must not have the same name as global scope objects. GoTo's are
<a name="l113"></a>rare and I don't want to slow the compiler and add code to fix this. You will
<a name="l114"></a>get errors if a collision happens, so it's not very dangerous, but the error
<a name="l115"></a>message is baffling.
<a name="l116"></a>
<a name="l117"></a>* The member names </span><span class=cF2>pad</span><span class=cF0> and </span><span class=cF2>reserved</span><span class=cF0> are special because multiple instances with
<a name="l118"></a>the same name are allowed in a class.

<a name="l120"></a>* Use </span><span class=cF2>reg</span><span class=cF0> or </span><span class=cF2>noreg</span><span class=cF0> in front of local var names to override automatic reg var
<a name="l121"></a>allocation. You can, optionally, specify a reg after the </span><span class=cF2>reg</span><span class=cF0> keyword.
<a name="l122"></a>
<a name="l123"></a>* Local non-reg function vars can be accessed in asm blks with </span><span class=cF2>&i[RBP]</span><span class=cF0> for

<a name="l139"></a>* Using </span><span class=cF2>try</span><span class=cF0>/</span><span class=cF2>catch</span><span class=cF0> in a function will force all local vars to </span><span class=cF2>noreg</span><span class=cF0>.
