Hello,

I'm currently trying to figure out how to make m4 only call macros within certain brackets, for example:

```
define(`test', '2')
test
->test

<test>
->2
```

It would be even better if this was possible.

```
define(`test', '2')
<test>
-><test>

<#test>
->2
```

Above is exactly what the `-H` flag does on GPP (Generic Preprocessor) (http://files.nothingisreal.com/software/gpp/gpp.html).

Any help would be great, thanks!
