It works for any method. $x.=lc, $x.=uc, $x.=flip, $x.=subst(‘for’,'bar’), whatever.

Just like $foo + 3 is different from $foo += 3, $foo.trans( ‘bar’ => ‘pog’ ) is different from $foo.=trans( ‘bar’ => ‘pog’ ). In the first instance $foo is not being modified, in the second it is.

Wouldn’t it have made more sense to call it trans= , by analogy to += , *= and so on? Or does trailing equal already have a different meaning?
