Redundant "result and result or value" in the code

[MeanSquaredError]

There are several places in the code where the expression result and result or value is used. So far I found these ones:

xmake/xmake/core/sandbox/modules/import/lib/detect/find_programver.lua

Line 73 in 766a7a8

return result and result or nil

(result and result or nil)

xmake/xmake/core/sandbox/modules/import/lib/detect/find_programver.lua

Line 111 in 766a7a8

detectcache:set2(cachekey, program, result and result or false)

(result and result or false)

xmake/xmake/core/sandbox/modules/import/lib/detect/find_program.lua

Line 335 in 766a7a8

return result and result or nil

(result and result or nil)

xmake/xmake/core/sandbox/modules/import/lib/detect/find_program.lua

Line 356 in 766a7a8

detectcache:set2(cachekey, name, result and result or false)

(result and result or false)

xmake/xmake/modules/lib/detect/find_package.lua

Line 100 in 766a7a8

detectcache:set2(cachekey, packagekey, result and result or false)

(result and result or false)

xmake/xmake/modules/lib/detect/find_package.lua

Line 126 in 766a7a8

return result and result or nil

(result and result or nil)

It seems to me that the result and result or value can be replaced just by result or value, since the two expressions are identical. For example result and result or nil could be replaced by result or nil

Or am I missing something?

It's equivalent, but this is an earlier style, and I haven't changed it yet to ensure consistent code style.

OK, thank you for the clarification.
