In Scala templates, how do I end a variable without a space?

I need to make a quick change to a page built in Scala in a Play app. Not really sure how to do this...

I have a variable @name that contains "foo" and I want to do this:

<div id="@name" class="@name_class">

and have it resolve to

<div id="foo" class="foo_class">

however Play is trying to look for a variable named @name_class

You can enclose with parenthesis, I haven't really tested with curly braces.

<div id="@name" class="@(name)_class"> ...

You can first concatenate the string and the display:

@val class_name = name + "_class"

And then assign:

<div id="@name" class="@class_name">

EDIT

As explained in the comment by @Chirlo the above will not work as of Play 2.1 you can put concatenation in a reusable block and use as such:

@mkClassString(name:String,tag:String):String = { name + tag }

and use it:

<div id="@name" class="@mkClassString(name,"_class")">

or use @defining as indicated by comment.

You can avoid a temporary variable with the following:

<div id="@name" class="@{name}_class"> ...
