New code block template syntax conflicts with underscore.js syntax
In Bottle 0.12-dev, rendering template which has line beginning with '<%' is producing SyntaxError . At least in 0.11.3, problem was not present. '<%= %>' is syntax for Underscore templates.
>>> bottle.__version__
'0.12-dev'
>>> from bottle import SimpleTemplate
>>> tpl = SimpleTemplate('<%=bla %>')
>>> tpl.render()

SyntaxError: invalid syntax
0.12 adds a syntax for code blocks, that seems to be in conflict with underscore.js. It will be possible to change the syntax for bottle templates, but that API is not public yet. I'll keep this bug open as a reminder.
the {{var }} syntax also interfere with vue.js I saw the document mentioned the template token is customizable (http://bottlepy.org/docs/dev/stpl.html "If you find yourself to escape a lot, consider using custom tokens." ) but its didn't explain how this can be done. Have to look into the source to figure out the parameter: template( "sometpl", template_settings={"syntax" :'<% %> % {| |}'} ) Could you add the parameter to the document ?
It's 2016, and many of the things in underscore.js have found their way into ES5 and ES6. So the fix might not be a a fix at all. Rather, developers today should opt for using more modern JS over underscore JS. As for the last comment of @zcattacz, can you just open this PR? Other wise I will do it.
