Tips for golfing in Burlesque
Using ".. .."wd instead of {".."".."}

If you need a Block of Strings such as {"abc" "def"} it is shorter to use the words built-in: "abc def"wd.

Using ra to parse fail-safe

ps will fail if the input is not properly formated or might produce unwanted results. In such cases, using ra is better. 

blsq ) "5,"ra
5
blsq ) "5,"ps
{5 ,}
blsq ) "5a"ps
{ERROR: (line 1, column 3):
unexpected end of input}
blsq ) "5a"ra
5


Using , to drop stdin

, is defined as a pop instruction if and only if there is exactly one element on the stack. It's used to pop STDIN from the stack when it's not needed but there (such as for example is the case on anarchy golf). 

Abusing the way mo is defined

mo is defined as 1R@\/?* and is used to generate a Block containing multiples of N:

blsq ) 3mo9.+
{3 6 9 12 15 18 21 24 27}


Yet due to side effects of ?* you can do some nasty things with it if you don't provide a number:

blsq ) "1"mo9.+
{"11" "21" "31" "41" "51" "61" "71" "81" "91"}

blsq ) {1 2 3 4}mo9.+
{1 4 9 16}
