List Subpages ordered by letter

Hi there,

Based on @zef 's following quote:

You can give this a try.

{{#each @c in ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z']
}}
## {{@c}}
{{{page where name =~ "^SomePage/" + replace(@c, /(.+)/, "$1")}}}

{{/each}}
