Lifetimes

this is a gimmicky very experimental feature which allows you to determine a variable's lifespan

for example in this snippet

egg x<2> = 5

the variable x will exist for 2 lines then will delete itself

egg x<2> = 5

putln(x) // 5
putln(x) // 5
putln(x) // error

output:

5
5
runtime error at 6:7: undefined variable: x

you can also use it with multi assignment and type annotation like so

egg a, b <3> int = 4, 2

putln(a) // 4
putln(b) // 2
putln(a) // 4
putln(b) // error

output:

4
2
4
runtime error at 7:7: undefined variable: b

important note

lifetimes tick based on statements executed, not on uses of that specific variable

Example:

egg x <2> = 1

putln(5) // 5
putln(2) // 2
putln(x) // error 

output:

5
2
runtime error at 6:7: undefined variable: x

this is because you have already used 2 statements so the variable x has already poofed
