The official Tcl implementation doesn't throw any errors at compile
time because it doesn't have one (not even in the sense that Perl5
does). As a compiler, we are left with two options:

1) Throw compile time syntax errors anyway because they're
arguably the Right Thing To Do.

2) Fake it and output code that throws an error at runtime.

Option 2 is probably the correct one to take, but it can easily be
made later. So for now we'll just go with option 1 because it's
implemented.

Here's an example that shows the difference:

puts hi
puts [set a 4

That outputs "hi\n" with tclsh before dying with the syntax error.
Partcl just dies without outputting anything.
