<p>Hi,</p>
<p>I've got a yaml file that will look something like this:</p>
<pre><code>---
hello: world
something: [{'values': { structB }, 'type': 'foo'}, {'type': 'bar', 'values': {.structB..}]
</code></pre>
<p>the 'something' key is a list, which has a top level dictionary while has a type key... Based on that struct, the values key will point to different structs.</p>
<p>How do you map to the different structs in golang? I know how to do it if there's only one static type:</p>
<pre><code>type graphconfig struct {
Graph string `yaml:"graph"`
Types [] XXX
Thing struct{
C int
D []int
}
}
</code></pre>
<p>But in the above case, I don't know how to express the "Types" element, so that it can be different things.</p>
<p>Thanks in advance!</p>

<pre><code>[]map[string]interface{}
