There are times when it is handy to access functionality and methods of the web framework from within a template being rendered. A primary use case of this is to figure out reverse URLs for rendering links within a page. Luckily, due to the fact that Go allows for functions as variables, we are able to do this quite easily. The first thing we have to do is formalize the tmplData anonymous struct to include a method that we would want to call from within the template. Go's template library supports execution of methods by name which allows us to call methods off of the data struct that is passed into the execute. With this in mind, we will expose a Reverse function in our template data struct in which we can pass in Echo’s Reverse function.
