The problem I have with those is that they are designed for

What if I wanted to make an email template instead?
Erb is like a Ruby preprocessor that can be used for any
format. It's used for many things in Ruby on Rails:
index.html.erb - Erb preprocessor, result is HTML
<% if foo %>
<li>asd</li>
<% end %>
bar.js.coffee.erb - Erb then CoffeeScript preprocessor, result
is JavaScript
<% if foo %>
bar = -> console.log("asd")
<% end %>
foo.text.erb - Erb preprocessor, result is plain text
<% if foo %>
asd
<% end %>
database.yml.erb - Erb preprocessor, result is YAML
development:
username: <%= username %>
password: <%= password %>
This really makes sense for D. It can be easily combined with D's
mixin capabilities to make it so you don't even need to implement
stuff like various loops:
<% [d code] %> -> [d code]
<%= [d expr] %> -> buffer.write([d expr]);
[text] -> buffer.write("[text]");
