They definitely might not understand the differences between the two
flavors well enough to know what to expect.  For example, warnings
from the byte compiler about "unused lexical variable" might be
extremely puzzling if those differences are not well understood,
because to someone who is used to dynamic binding, the code looks 100%
legit.
