Reproducer

Put the following snippets to a file with .pl extension and open in kakoune. Or paste and issue :set buffer filetype perl

$dirs{purpose}{type};  # nested hash wrong highlighting
    s{from}{to};       # confused with substitution

$time_from/$divided/$divided_again;  # division wrong highlighting
         m/regex/;                   # confused with regex match

# 1st: confuses division with // match
# 2nd: semicolon statement separator not honored
# 3rd: comment not honored
$timely/$divided/$divided_again/$and_again;  # // match
       /regex/;                              # confused with regex match
