[Petal] strange behaviour

[Fergal Daly]

this template

<t>
a = <t petal:replace="a"/> *** 
    <t petal:define="a string:hello">
a = <t petal:replace="a"/>
    </t>
</t>

doesn't seem to work correctly. The define doesn't seem to have any effect. If 
you remove the line with *** it works fine. Any ideas? The generated code 
looks fine,
