Comment(by jdemeyer):
Replying to [comment:45 davidloeffler]:
> Is that supposed to be {{{("y")}}} or {{{("'y'")}}} perhaps?
No, {{{'y}}} is correct. I have added some comments to that code in the
patch.
Basically, the {{{'y}}} syntax is PARI's way of refering to a ''variable''
(as opposed to the ''value'' of a variable). See the following `gp`
session:
{{{
gp> y = 42
%1 = 42
gp> y
%2 = 42
gp> 'y
%3 = y
gp> subst(x^3, x, y)
%4 = 74088
gp> subst(x^3, x, 'y)
%5 = y^3
}}}
