Both those mechanisms are very predicable in their effect on source code. In those cases, a pre-parse of the source code could yield information which could be easily used by the static analyzer.
That would be quite a pre-parse, even for the simplest cases.

In most cases, though, the parse-affecting statement occurs in another file, whose very location may require executing some of the perl code to determine. Or in XS.
