How to assign a variable to an evaluated string

Consider this template code:


<#assign useOranges=false>
<#assign fruit>
    apples,
    bananas,
    <#if useOranges>
        oranges
    </#if>
</#assign>
<#assign arr=fruit?split(",")>
${arr?size}<br />
${fruit}


This outputs:
3
apples, bananas,

What I want is for ${arr?size} to print 2 rather than 3: i.e., for the contents of fruit to be evaluated before assigning it to arr. I've tried adding:

<#assign fruit2>${fruit}</#assign>
<#assign arr=fruit2?split(",")>

I also tried the eval built-in:

<#assign fruit2>${fruit?eval}</#assign>
<#assign arr=fruit2?split(",")>

Neither of these produce the desired output. Is there a way to do this in FreeMarker?
