Feature Request: Support case conversion like {{name.uppercase}} or {{name | lowercase}}
Adding additional modifiers when using names or other text-related patterns. I think it could be 2 styles.

Style 1 using `.`:
- {{name.uppercase}}
- {{name.lowercase}}
- {{name.capitalize}}

Style 2 using `|`:
- {{name | uppercase}}
- {{name | lowercase}}
- {{name | capitalize}}
