I found these snippets:

https://psalm.dev/r/8e58844e60

<?php

function go(string $code): void
{
  eval(str_replace('<?php', '', $code));
}

Psalm output (using commit f315647):

ERROR: UnusedFunctionCall - 5:8 - The call to str_replace is not used

I came across a similar-looking UnusedVariable false positive: https://psalm.dev/r/d1a6dffdd6

Note that the if statement is required. If the variable assignment and eval are placed at the top level or directly inside a function body, there is no UnusedVariable error.

I found these snippets:

https://psalm.dev/r/d1a6dffdd6

<?php

if (rand()) {
    $v = '';
    eval($v);
}

Psalm output (using commit 293b728):

INFO: UnusedVariable - 4:5 - $v is never referenced or the value is not used
