I have created a minimal site+theme that demonstrates what I think is a common use case: using layouts to change the rendering of section index pages.

The theme has three page templates in layouts:

• single.html is a single page
• list.html uses pagination
• section.html is a stripped-back single page, to introduce a section without listing its contents

The site has three sections, uses-section, uses-list, uses-single, which use each of these:

• uses-section/_index.md is just a simple index file in a section root
• uses-list/_index.md is the same, with layout = 'list'
• uses-single/_index.md has layout = 'single'

This works as expected in v0.145 (each template includes its name surrounded by == signs):

% git clone https://github.com/tastapod/template-order && cd template-order

% hugo@145 --cleanDestinationDir --quiet && grep -r == public | grep uses

public/uses-section/index.html:== section ==
public/uses-list/index.html:== list ==
public/uses-single/index.html:== single ==

but in v0.146, all three render with section.html:

% hugo@146 --cleanDestinationDir --quiet && grep -r == public | grep uses

public/uses-section/index.html:== section ==
public/uses-list/index.html:== section ==
public/uses-single/index.html:== section ==

Am I just Doing This Wrong™?
