While there are ways to work around nesting to a known depth, it gets
ugly quickly, and nesting to an arbitrary depth is beyond the ability
of regexes to match directly.
What you can do is write a parser that uses regular expression and
additional code to find the substring you are searching for.
search for "function"
set nestingLevel to 0
in a loop search for /[{}]/ opening a closing delimiter
if you find a { increment nestingLevel
if you find a } decrement it
when nesting level hits 0 again you are done
