That seems quite impractical, considering that the function body may be
in a language that has little in common with SQL even at the lexical
level. The SQL parser couldn't even tell what was a comment or quoted
string with any reliability.

Would you be unhappy if "language" appearing in what you think is a
comment in the function body caused a failure? How about "language"
in what you think is a quoted literal string?
Another problem is that the CREATE FUNCTION syntax doesn't insist on any
particular ordering of the attributes; there's nothing saying that
LANGUAGE must be the first thing after the AS clause.
