Line 185:

:Because of [[Module:String#L-402--L-404|lines 402–404]]. The reasoning for that code is not, so far as I can tell, documented. There is similar code, also not documented, in <code>find()</code> but that code makes some sort of sense – find anything in an empty string should return <code>0</code>. Makes me wonder if <code>replace()</code> was created after <code>find()</code> and used <code>find()</code> as an armature upon which to construct <code>replace()</code>. Seems to me that [[Module:String#L-402|line 402]] could be rewritten as: <syntaxhighlight lang="lua" inline="1">if '' == pattern then</syntaxhighlight>. But, are there any templates out there that rely on this anomaly?

::Function <code>replace()</code> [[Special:Diff/540121093|was added on 24 February 2013]], two days after [[Special:Diff/539690696|function <code>find()</code> was added]]. The early return in <code><nowiki>if source_str == '' or pattern == '' [...]</nowiki></code> was added in between those edits: [[Special:Diff/540073010]]. —⁠[[User:Andrybak|andrybak]] ([[User talk:Andrybak|talk]]) 14:10, 12 July 2025 (UTC)
