commit 31fc7cc5aca8512d49515cb42aca921f601db277
Author: Matthew Horsfall <wolfs...@gmail.com>

Add indented here-docs.
This adds a new modifier '~' to here-docs that tells the parser
that it should look for /^\s*$DELIM\n/ as the closing delimiter.
These syntaxes are all supported:
<<~EOF;
<<~\EOF;
<<~'EOF';
<<~"EOF";
<<~`EOF`;
<<~ 'EOF';
<<~ "EOF";
<<~ `EOF`;
The '~' modifier will strip, from each line in the here-doc, the
same whitespace that appears before the delimiter.
Newlines will be copied as is, and lines that don't include the
proper beginning whitespace will cause perl to croak.
Some examples:
if (1) {
print <<~EOF;
Hello there
EOF
}
prints "Hello there\n";
The following:
if (1) {
print <<~EOF;
Hello There
EOF
}
croaks with:
Indentation on line 1 of here-doc doesn't match delimiter at - line 2.
