Re: How do I find the missing curly brace??

Use perl to find perl errors.

#!/usr/bin/perl

use strict; # https://perlmonks.org/?node_id=11163431
use warnings;

my @what_lines;

@ARGV = '3raindeermaze.pl'; # FIXME

while( <> )
  {
  for ( split // )
    {
    /\{/ ? push @what_lines, $. :
    /\}/ ? pop @what_lines : 0;
    }
  }
print "line numbers with unmatched { => @what_lines\n";

Comment out the ARGV line to use your file as the argument to the program.
( I just did that for testing. )

consider this convoluted example (Perl would catch this anyway)

sub bla { 
    print "yadda";
    my %hash = {
        foo => 1,
    );
}

the problem is in line 3, but your code will report line 1.

and if you add a # } after a comment in line 2 it won't report anything.
