I don't like single quotes and double quotes as delimiters, as the start character and end character are not distinguishable, and can't be matched or nested. But I do like the backtick ('`') as an escape character. In general, I like being able to type as much as possible without using the shift key.

  amptp{
    culture[en_US];
    nice[36];
    name[Bank of America];
    host[Accounts]
    node[/Management/Details];
    data{
      [view][statement];
      [year][2017];
      [month][Feb];
      [page][2];
      [section][debits];
      [anchor][`[15`]];
    }
  }

This roughly translates as

https: //accounts.bankofamerica.com/Management/Details?view=statement&year=2017&month=Feb&page=2&section=debits#%5B15%5D

Compacted comparison:

amptp{culture[en_US];nice[36];name[Bank of America];host[Accounts]node[/Management/Details];data{[view][statement];[year][2017];[month][Feb];[page][2];[section][debits];[anchor][`[15`]];}}
