Github read me says: https://github.com/kirbysayshi/vash#the-transition-character
Vash uses the @ symbol to transition between code and markup.
To escape and print a literal @, use a double @, like this: @@.
If that doesn't work, use the html entity: & # 6 4 ; So: test & # 6 4 ;test.com. (without spaces).
