I would say that the number of available functions is not
necessarily a sign of complexity. The Seed7 interpreter
and the compiler are both much bigger than the P4 and
even the Pascal 6000 compiler. OTOH most of the parsing
in Pascal compilers is usually hard wired in the compiler,
while almost all of the syntax and semantic analysis in
Seed7 is data structure driven and configurable at compile
time (otherwise user defined statements and operators
would just not be possible).

So it is an apples to oranges comparison. Simplicity and
elegance of design aggainst flexibility to define new
constructs in a wide range.

There are similarities as well: All the data structure
driven syntactic and semantic analysis of Seed7 programs
is done with LL(1). That would be exactly in the Pascal
tradition and allows the Seed7 interpreter to analyze
a program (the process necessary to generate an internal
representation which can be interpreted) with approx.
200000 lines per second.
