This is related a little to #5220, but tangentially.
In sage-3.3.alphpha5 the following is now COMPLETELY BROKEN:
{{{
@interact
def f(s=(0,pi,1)):
print s
}}}
Basically anything involving symbolics in ranges is broken. If you try
this in the console you'll see the reason:
{{{
sage: @interact
....: def f(s=(0,pi,1)):
....: print s
....:
<html><!--notruncate--><div padding=6 id='div-interact-0'> <table
width=800px height=20px bgcolor='#c5c5c5'
cellpadding=15><tr><td bgcolor='#f9f9f9' valign=top
align=left><table><tr><td align=right><font
color="black">s </font></td><td><table><tr><td>
<div id='slider-s-0' class='ui-slider ui-slider-3'
style='margin:0px;'><span class='ui-slider-handle'></span></div>
</td><td><font color='black'
id='slider-s-0-lbl'></font></td></tr></table><script>(function(){ var
values = ["
0","
1","
2","
3","pi"]; setTimeout(function() {
}}}
Notice that the range values -- 0, 1, 2,3, etc., are symbolic and printed
via ascii art. This is thus a similar problem. It is I think a massive
bug -- it causes mysterious hangs in numerous natural situations.
