If I type something like this in a messagebox:
list +1 +1 +1 -1 -1 -1 -1 +1
then should the +1 be floats or symbols?
(currently, they're symbols)

Dunno which is should be, but the 'c' language doesn't allow unary '+' in front of numerical literals... so I followed that lead.

I don't know which C language you are talking about. Try compiling the following program with options -ansi -pedantic-errors:
#if + +1 int main (void) { int foo[+ +1] = { + + + + + + + + + + +1 }; return foo[0]; } #endif
This demonstrates that unary + works in front of numerical literal, both in the main language and in the preprocessor. I don't know of a way to test whether the last + before the 1 is actually considered part of the literal or not. However, both scanf() and strtod() consider + as part of a float literal (was there ever a time that they didn't? really?).

What would be the advantages/disadvantages of either way? My
intuition says that +1 should be a symbol, perhaps because it is
rare to write positive numbers in math with a leading +.
Maybe the errant newbie might be confused when +1 turns out to be a
symbol. But if Pd starts removed + signs upon save, then that could
also be annoying.

well, pd is not the only program, that has to handle string to float conversions ... most parsers i know, would allow a leading '+' char for parsing floats ...

symbol. But if Pd starts removed + signs upon save, then that could

maybe the newbie is confused by +1 being a symbol? or, if he's not confused by +1 being a symbol, then probably by 1e+2, being a float ..

There's no such entity as "most people". These are generalities. All generalities are meaningless. You've got to pin it down to a specific person doing a specific thing at a specific time and space. William S. Burroughs

Intuition is something that is trained. If you trained that part of your intuition using pd and not much else, you may get to see "+1 is a symbol" as something normal, obvious, and the way it should be. People with different experience may get to think otherwise. The leading + is recognised in float literals in almost all programming languages; actually, only pd works like that, if I think only of contemporary languages that were designed for doing real work.
But if Pd starts removed + signs upon save, then that could also be annoying.
Pd already removes a lot of things. e.g. 1000001 becomes 1e+6, and so does 1000002, ...
