+## 3a. Use sigils for code mode, use `{`/`}` for keys
+
+Similar to 3, but uses braces instead of `[`/`]` square brackets for keys, reducing variation and
+the need for additional pattern escapes.
+See Slack thread.
+
+Requires `#` to be escaped in unquoted patterns.

+#input {$var :function option=value}
+Hello {$var}
+
+#input {$var :function option=value}
+#local $foo = {$bar :function option=value}
+Hello {$var}, you have a {$foo}

 ## 4. Reducing keywords
 
 Avoids keywords in favor of sigil based parsing.
