In perlfunc#Perl-Functions-by-Category do is only listed under "Keywords related to Perl modules", which might explain the API.¹

Also looked into perlglossary which mentions looks-like-a-function only once under the title pseudofunction .

Surprisingly there is not one other perldoc mentioning pseudofunctions !?!

But actually this helps fixing the bug in B::Deparse, cause the handling of other pseudofunctions could be mimicked for do FILE .

¹) NB: eval is listed under "Keywords related to the control flow" ;-)

or we're going to identify a whole new problem group ;´D

perlglossary was imported from the Camel III (with permission) so sometimes has terminology differences from the rest of the perldoc.
