the correct rule is: tabs to indent, spaces to align

[TAB][TAB][TAB]ShortTypename[SPACE][SPACE]variable_name

[TAB][TAB][TAB]LongLongLongTypename[SPACE]variable_name2

ps. the [SPACE] counts above are illustrative, not accurate.

The correct rule is: you shouldn't align.

[hollerith]

The code I maintain (Emacs Lisp) follows that rule.

Exactly, just have your linter error out if there's a tab following a space

[pepa65]

And ever stronger if a space follows a tab..!

[g-b-r]

That's how you do alignment (in indented parts)

[TZubiri]

Just imagine pressing the space bar 12 times for each line, or having to use :vimq! to handle that without going crazy
