TYPO3 Core

Using a typoscript condition like `[globalVar = LIT:0 = {$someConst}]` never evaluates to true.

The reason is that the internal processing of LIT:0 results in a null value for the left side of the comparison.
This causes an evaluation of if (null '0'), which is by definition [1] false.
(mind that if (null 0) would result in true)

The solution is to correctly evaluate LIT:0 to be '0'.

How to test:

[globalVar = LIT:0 = 0]
page.30 = TEXT
page.30.value = never shown
[end]
