Another example of bad syntax: the other day I tried redo within a do {} until block, but Perl complains that I could not use redo outside a loop block, which means Perl does not take do {} until as a loop block.
That is documented behaviour (see perlsyn), though I must agree not very consistent. It applies not only to do {} until but also to do {} while. perlsyn suggests a workaround like this 
do {{
  next if /^#/;
  # do something
}} until /^\s*$/;

but you have to adjust this to be able to use last.

My suggestion is to not use those constructs altogether and instead emulate them with bare blocks and redo ... 

# do {} while condition
{
  # some code
  redo if condition;
}

# do {} until condition
{
  # some code
  redo unless condition;
}
