String slice elegant way

Mage [mailto:mage@mage.hu]

#a = 'hello there'
#and I need 'llo there'

···

#
#a[2,a.size] works, but I find it ugly because the given length
#is larger
#than the real length of the result.
#a[2,a.size - 2] is okay, but it is not DRY.
#
#Is there any elegant way, like a[2:] in Python?

is a[2..-1] good enough?

2

this is the closest I could think of:

a = "hello there"
a[-9,9]

···

llo there
