Excepting 't'. In the function body use of 't' where it is otherwise not 
defined results in:

File 'wham.inc' line 19:
Parse Error:
Expected 'operand', 't' found instead
Fatal error in parser: Cannot parse input.
Render failed

Aside: I've been playing with other stuff most of the day, but
we have too that function { pattern {} } mode where you don't - cannot - 
specify an argument list for the function. In that case I expect all the 
values are whatever was passed to 'pattern' for x|u,y|v,z. Should verify 
u and v set to x and y I guess, but expect that the case.
